Only one of these plasticizers may be used alone, or two or more of these plasticizers may be used in combination. Since the plasticizer does not react with other components in the photosensitive resin composition and is extracted into the solvent ink during printing, the content is preferably low.

[2-10. Ink repellent]
Examples of the ink repellent include silicone oil containing a siloxane unit (hereinafter, simply referred to as silicone oil), a silane coupling agent, a silane compound, silicone rubber, and a silicone resin. Of these, silicone oil is preferable because the transparency of the photosensitive resin composition and the cold flow resistance of the photosensitive resin composition can be achieved in a well-balanced manner.

Although the molecular structure is not particularly limited, as the ink repellent, a compound having a polyalkylsiloxane in the main chain such as polydimethylsiloxane or polydiethylsiloxane can be mentioned as a preferable compound. Further, the ink repellent may be a compound having a polysiloxane structure in a part of the molecule. Further, as the ink repellent, a compound in which a specific organic group is introduced into the polysiloxane structure can be used. Specifically, as the ink repellent, a compound having an organic group introduced into the side chain of the polysiloxane, a compound having an organic group introduced into both ends of the polysiloxane, and a compound having an organic group introduced into one end of the polysiloxane.

[3. Condition data]
The exposure condition indicated by the condition data may be, for example, at least one of the exposure time, the exposure amount, the environmental temperature, and the temperature, thickness, and transmittance of the photosensitive resin composition to be exposed.

[4. Characteristic data]
The characteristics shown in the characteristic data include, for example, MPD (Minimum Printed Dot), white depth, white line width, minimum independent point formation size, independent line width, development speed, cold flow property, melt viscosity, hardness, and tensile elongation. Degree, tensile strength, tackiness, chipping resistance, abrasion resistance, washout resistance, surface abnormality resistance, film peeling property, adhesiveness, ink concentration on printed matter, hiding property, edge scraping, step, and ink removal It may be at least one of the sexes.

The MPD is, for example, the minimum halftone dot area ratio when halftone dots are formed with a predetermined exposure amount and a predetermined number of lines (LPI: Line per inch). When the dot height becomes the same as the solid portion height, it may be determined that halftone dots are formed. MPD means that the smaller the value, the higher the resolution.

The whiteout depth is, for example, the height from the bottom surface to the surface of the printing plate after the unexposed portion having a predetermined line width is developed and dried. As an example, a printing plate is made using a negative film having a fine line with a width of 1500 μm, and the depth in the depth direction is measured using a depth height measuring machine (Nissho Precision Optics, μDEPTH & HEIGHT MEASURING SCOPE). It may be a white depth. The deeper the white depth, the better.

The white line width is, for example, the line width after developing and drying an unexposed portion having a predetermined line width. The white line width is preferably the same as the negative design.

The minimum independent point formation size is, for example, the diameter of the minimum dots formed by exposing, developing, and drying circles having different diameters. The minimum independent point formation size should be small.

The independent line width is, for example, a line width after developing and drying an exposed portion having a predetermined line width. The independent line width is preferably the same as the negative design.

The development speed is an index indicating, for example, the development time when the amount of change in thickness before and after development becomes a reference value. When developing while transporting a raw photosensitive resin composition, that is, an unexposed photosensitive resin composition, the development speed is the transport speed when the amount of change in thickness before and after development becomes a reference value. It may be the reciprocal. As an example, a raw plate having a thickness of 4.00 mm and a plane size of 5 cm × 5 cm was developed under three conditions of feeding speeds of 75 mm / min, 100 mm / min, and 150 mm / min, and the thickness was measured after drying at 60 ° C. for 2 hours. In this case, the development speed may be the inverse of the feeding speed at which the amount of change is 1.6 mm from the calibration curve between the feeding speed and the amount of change in thickness before and after development. The exposure amount may be an arbitrary reference exposure amount, and the length of the irradiation region in the transport direction may be an arbitrary reference length. The faster the development speed, the better.

The cold flow property may be, for example, the degree of change in thickness when the photosensitive resin composition of a raw plate is left at room temperature. As an example, the cold flow property is the amount of change in thickness after a photosensitive resin laminate having a thickness of 4.00 mm and a plane size of 5 cm × 5 cm is stored at 40 ° C. for 1 week under a load of 700 g. It's okay. It is better to have less cold flow.

The melt viscosity is, for example, a resin viscosity measured using a rheometer at a predetermined temperature (160 ° C. as an example). The lower the melt viscosity, the better the fluidity and the easier it is to mold. The melt viscosity may be a melt flow rate (g / 10 min) measured using a melt indexer L247 (TECHNOL SEVEN) under the conditions of a measurement temperature of 200 ° C. and a load of 5.0 kg.

The hardness may be the hardness after exposure or the hardness before exposure. For example, after leaving a printing plate with a thickness of 3.94 mm in a constant temperature and humidity chamber with a temperature of 23 ° C and a relative humidity of 50% for one day, the JIS constant pressure loader GS-710 (manufactured by Teclock Co., Ltd., Durometer) It may be a value measured using GS-719G ASTM: D2240A, JIS: K6253A, ISO: 7619A). The hardness may be the Shore A hardness after applying a load (mass 1 kg as an example) to the solid surface for 15 seconds.

The tensile elongation is, for example, the elongation measured by a tensioning machine for a photosensitive resin composition after exposure. The higher the tensile elongation, the more difficult it is for the resin to break and the harder it is to break.

The tensile strength is, for example, the strength measured by a tensile machine for a photosensitive resin composition after exposure. The higher the tensile strength, the harder the resin.

The tackiness is adhesiveness, and may be, for example, the degree of stickiness of the surface of the printing plate after exposure. The tackiness may be measured by a tack tester or evaluated by a tactile sensory test.

The chipping resistance is, for example, an index indicating the ease of chipping of a printing plate. FIG. 2 shows a method for measuring chipping resistance. For chipping resistance, a printing plate 41 made of a diamond-shaped relief pattern 40 having a length of 1.5 cm, a width of 1 cm, and a thickness of 2.5 mm is erected, and the blade 42 is vertically dropped along the printing surface to collide with the relief pattern 40. It may be the ratio of the chipped area of the relief pattern 40 when it is made to run. The blade 42 extends in the vertical direction facing the printing surface, and may have a shape that projects toward the printing surface toward the upper portion, and is dropped from a height of 60 cm while being guided. The smaller the chip resistance, the better.

The abrasion resistance is, for example, the abrasion resistance of a printing plate. As an example, the abrasion resistance is NP type printing resistance tester (manufactured by Shinmura Printing Co., Ltd., trade name, contact body: cloth, size 8 cm ×) for a printing plate containing characters with a size of 8 to 12 points. It may be the degree of destruction of characters when the contact body is rubbed 300 times with (6 cm, load 1 kg). The degree of destruction may be observed with a microscope, and if the characters are not destroyed, the evaluation may be ◯, and if the characters are destroyed, the evaluation may be ×.

The washout resistance is, for example, the likelihood of missing dots when a printing plate having fine print (6 to 12 points as an example) is developed and the uncured portion is washed out. As an example, washout resistance may be assessed by the number of chips.

The surface abnormality resistance is resistance to surface abnormalities that occur when the printing plate swells due to a solvent during development and the printing plate shrinks after drying. As an example, the surface abnormality resistance may be an evaluation of the presence or absence of surface abnormality when developed using perchlorethylene or the like having a strong swelling property as a solvent.

The film peelability may be, for example, the adhesiveness between the photosensitive resin composition and the cover film. When a slip layer or a black mask layer is provided on the surface of the photosensitive resin composition, the film peelability may be the adhesiveness between these layers and the cover film. As an example, the film peelability may be an evaluation of the ease of peeling when the cover film is peeled from a photosensitive resin laminate having a plane size of 2.54 cm × 10 cm. The film peelability may be the tensile adhesive strength when Autograph AGS-100G (manufactured by Shimadzu Corporation) is used and the crosshead speed (test speed) is 50 mm / min. The film peelability is preferably within the reference range, and may be too high or too low than the reference range.

The adhesiveness may be, for example, adhesion between the photosensitive resin composition and the base film. The higher the adhesiveness, the better. Adhesiveness may be evaluated and measured in the same manner as film peelability.

The ink density with respect to the printed matter may be, for example, the ink density of the printed matter using the printing plate. As an example, the ink density may be measured by Spectroeye (manufactured by Sakata Inx Engineering Co., Ltd., trade name).

The concealing property is an index of whether or not the ink is uniformly printed on a printed matter using a printing plate and the base is covered. The concealment property may be evaluated visually with a microscope or the like. The concealment property is better as the ratio of concealment is larger.

The edge blurring may be, for example, the ink transferability of the edge in a solid printed matter using a printing plate. Edge cassoulet may be evaluated visually.

The step is an index of whether the bonded portion between the liner and the core of the printed surface becomes darker than the non-bonded portion when printing on corrugated cardboard using, for example, a printing plate. Since the presence or absence of backing by the core is different between the bonded portion and the non-bonded portion, the way the dots are crushed during printing is different, and the ink transfer area is different. For the steps, Wasser Super Z Plus 3L (Osaka Printing Ink Mfg. Co., Ltd., trade name) is used as the ink, A-step sheet (core 160 g) and 250 lpi Anilox roll are used as the printed matter, and the printing speed is 60 sheets / 10 sheets may be flexographically printed in minutes and the halftone dots of the printed matter on the last sheet may be evaluated. The printing plate may have a thickness of 4.00 mm, and as an example, a printing plate developed using a negative film pattern having 10% (size: 10 cm × 75 cm) halftone dots with a line number of 30 lpi. Alternatively, a printing plate developed by full curing (size: 10 cm × 75 cm) may be used. The step may be the difference between the maximum value and the minimum value of the ink transfer area ratio in the vertical direction (print area ratio difference). The print area ratio may be calculated for each of the 20 groups in the direction perpendicular to the bonded portion when 9 halftone dots of the printed matter are grouped. The print area ratio may be calculated using an image analyzer (LUZEX). The smaller the steps, the better.

The ink repellent property is, for example, the amount of ink remaining on the printing plate after printing. The ink repellent property may be evaluated visually.

In step S11, the control unit 311 causes the manufacturing apparatus 2 to manufacture the photosensitive resin composition. When the treatments of steps S11 to S15 are performed a plurality of times, the control unit 311 may carry out the production by changing the composition of the photosensitive resin composition each time.

In step S13, the composition acquisition unit 301 and the characteristic acquisition unit 303 acquire the composition data and the characteristic data of the photosensitive resin composition produced in the process of step S11, respectively. When the photosensitive resin composition is exposed, the condition acquisition unit 302 may further acquire condition data. The composition acquisition unit 301 may acquire the composition data from at least one of the operator and the manufacturing apparatus 2, or may acquire the composition data from another external apparatus (not shown). The condition acquisition unit 302 may acquire the condition data from at least one of the operator and the exposure device (not shown), or may acquire the condition data from another external device (not shown). The characteristic acquisition unit 303 may acquire the characteristic data from at least one of the operator and the measuring device (not shown) for measuring the characteristic, or acquire the characteristic data from another external device (not shown). You may. The measuring device may be arranged outside the manufacturing apparatus 2 or may be arranged inside. The properties may be acquired at multiple positions in the photosensitive resin composition. The characteristic acquisition unit 303 may acquire characteristics at least one before and after exposure. Of the processes in step S13, the composition data acquisition process may be performed before the process in step S11.

In step S15, the learning processing unit 304 executes the learning process of the model 305 using the learning data including the acquired composition data and characteristic data. The learning processing unit 304 may perform learning processing using learning data further including conditional data. The model 305 is a neural network such as a recurrent type or a time delay type as an example in the present embodiment, but other machines including a random forest, gradient boosting, logistic regression, and a support vector machine (SVM). It may be a learning algorithm. For example, model 305 may include nodes in the input layer corresponding to each element of the training data and nodes corresponding to each raw material in the recommended composition in the output layer. There may be one node or a plurality of nodes in the input layer for one element of the training data. An intermediate layer (hidden layer) containing one or more nodes may be interposed between the input layer and the output layer. The learning processing unit 304 may execute the learning processing by adjusting the weight of the edge connecting the nodes and the bias value of the output node.

[5-2. Model operation processing]
FIG. 4 shows a method for producing a photosensitive resin composition using the model 305. System 1 manufactures a photosensitive resin composition by the treatment of steps S21 to S27.

In step S21, the target characteristic acquisition unit 306 acquires the target characteristic data of the target photosensitive resin composition. Further, the scheduled condition acquisition unit 307 may acquire scheduled exposure condition data indicating the planned exposure condition. The target characteristic data may include the target range of the characteristic for at least one characteristic. The target range may be defined by at least one of an upper limit value and a lower limit value.

In step S23, the target characteristic supply unit 308 supplies the acquired target characteristic data to the model 305. Further, the scheduled condition supply unit 309 may supply the scheduled condition data to the model 305.

In step S25, the recommended composition acquisition unit 310 acquires the recommended composition data output by the model 305 in response to the supply of the target characteristic data (or the target characteristic data and the scheduled condition data) to the model 305. The recommended composition acquisition unit 310 may generate a plurality of partial target characteristic data by bagging the target characteristic data (also referred to as bootstrap aggregating) and sampling only a part of the target characteristics. The recommended composition acquisition unit 310 may supply a plurality of partial target characteristic data to the model 305 to acquire a plurality of recommended composition data. The recommended composition acquisition unit 310 collects the acquired recommended composition data to show the composition that can achieve the target of all the characteristics in the target characteristic data, and the achievement of the target for at least a part of the characteristics. You may get a pair with a probability. The target achievement probability may be a synergistic value of the achievement probabilities of all the characteristics, and as an example, the achievement probabilities of all the characteristics may be weighted by the weighting coefficient of each characteristic and synergistic. The recommended composition acquisition unit 310 may acquire a set of the recommended composition data and the probability distribution of at least one characteristic value by using the target characteristic data including the target range of the characteristic.

In addition, the recommended composition acquisition unit 310 may acquire recommended composition data by repeatedly using the model 305 using a genetic algorithm. For example, the recommended composition acquisition unit 310 supplies target characteristic data (or partial target characteristic data) to the model 305 to acquire a plurality of recommended composition data, and then selects, crosses, and crosses the recommended composition data. And mutations may be performed to generate multiple recommended composition data for the next generation. Crossover may, by example, swap the content of at least some of the raw materials between the two recommended composition data. Mutation may be to change the content of at least some of the raw materials in the recommended composition data. The recommended composition acquisition unit 310 supplies the generated next-generation recommended composition data to the model 305 to acquire a plurality of characteristic data, and among the plurality of recommended composition data supplied to the model 305, all the characteristics satisfy the target. Recommended composition data may be extracted. After that, the recommended composition acquisition unit 310 performs any of selection, crossover, and mutation on the extracted recommended composition data to generate a plurality of next-generation recommended composition data, and the characteristic data among the recommended composition data is generated. By repeating the process of extracting the recommended composition data satisfying the target, the recommended composition data in which the achievement probability of the target exceeds the reference probability may be acquired.

In step S27, the control unit 311 supplies the recommended composition data to the manufacturing apparatus 2 to manufacture the photosensitive resin composition with the composition indicated by the recommended composition data. When the control unit 311 acquires a plurality of recommended composition data from the recommended composition acquisition unit 310, the control unit 311 displays the recommended composition data and supplies any one of the recommended composition data selected by the operator to the manufacturing apparatus 2. You can do it. In this case, the control unit 311 may display the acquired plurality of recommended composition data in descending order of the probability of achieving the target. When the operator selects any one of the characteristics, the control unit 311 may display a plurality of recommended composition data in descending order of the probability of achieving the target of the characteristic.

In the manufacturing apparatus 2, the composition of the photosensitive resin composition to be manufactured is determined based on the recommended composition data acquired from the learning processing apparatus 1, and the raw materials (components) corresponding to the determined composition are mixed to form the photosensitive resin composition. You may manufacture things. As an example, the components of the photosensitive resin composition may include a solvent that dissolves other components or a dispersion medium that disperses the other components, and the mixing unit 20 of the manufacturing apparatus 2 mixes each component and is photosensitive. The fluid (coating liquid) of the sex resin composition may be adjusted. Further, in the manufacturing apparatus 2, the fluid of the mixed photosensitive resin composition may be applied onto the base film. After the photosensitive resin composition is applied, the manufacturing apparatus 2 may remove the solvent and the dispersion medium by drying. As a result, a laminate of the base film and the film-like photosensitive resin composition is produced. The manufacturing apparatus 2 may manufacture a photosensitive resin laminate by providing a cover film for protecting the photosensitive resin composition on the photosensitive resin composition. At least one of the composition determination based on the recommended composition data, the mixing of the components, and the production of the laminate may be performed by the operator without using the production apparatus 2. Further, after the production of the photosensitive resin composition, the model 305 may be relearned by the treatments of steps S1 to S15 described above.

[6. How to use the photosensitive resin composition]
FIG. 5 shows a method of using the laminate 100 of the photosensitive resin composition. In the present embodiment, as an example, a printing plate for flexographic printing is formed using the laminate 100. In the drawings, (1) to (5) show the main steps for forming the printing plate, the upper part of (1) to (5) shows a cross-sectional view, and the lower part shows a plan view. Further, in the present embodiment, as an example, the laminate 100 has a base film 101, a photosensitive resin composition 102, a black mask layer 103, and a cover film 104 in this order from the back surface side.

First, as shown in (1) and (2), the laminated body 100 as a raw plate is irradiated with active rays through the base film 101 to provide the cured layer 106. For example, exposure, so-called back exposure, is performed through a base film 101 made of a polyester film, and the back surface side of the photosensitive resin composition 102 is photocured to provide a thin and uniform cured layer 106. The "uniform cured layer" means that the difference between the maximum thickness and the minimum thickness of the cured layer is 0.10 mm.

Next, as shown in (3), after removing the cover film 104 from the laminated body 100, the black mask layer 103 is removed in the negative shape of the print pattern by irradiating the laser beam from the surface side of the laminated body 100. As a result, the photosensitive resin composition 102 is exposed to the positive shape of the print pattern on the surface of the laminate 100.

Next, as shown in (4), exposure is performed by irradiating active light rays from the surface side of the laminated body 100. As a result, the photosensitive resin composition 102 is cured in the positive shape of the print pattern. At this time, the active light beam may be irradiated from the back surface side of the laminated body 100 as well.

Here, in the steps (2) and (4), for example, a high-pressure mercury lamp, an ultraviolet fluorescent lamp, a carbon arc lamp, a xenon lamp, sunlight and the like can be used as the light source of the active light. The central wavelength of the active light may be 320 nm to 380 nm, preferably 330 to 380 nm, and more preferably 340 to 380 nm from the viewpoint of improving the efficiency of the chemical reaction. The central wavelength of the active light can be controlled within the above numerical range by using a wavelength cut filter.

It may be preferably 85% or more, more preferably 90% or more. The exposure distribution of the active light can be controlled to 80% or more by adjusting the distance between the light sources of the active light and the distance between the light source and the photosensitive resin layer. The average irradiation intensity of active light, from the viewpoint of shortening the exposure time may be at 10 mW / cm ² or more, preferably 11W / cm ² or more, may be at more preferably 12W / cm ² or more. The irradiation intensity of the active light means the ultraviolet intensity in the UV-A region. The average irradiation intensity of the active light can be controlled to ^{10 mW / cm 2} or more by adjusting the output of the light source and the distance between the light source and the photosensitive resin.

Further, when the laminate 100 is placed on a predetermined substrate and irradiated with active light in the steps (2) and (4), the temperature in the exposed surface of the substrate is taken from the viewpoint of the stability of the chemical reaction. The difference between the maximum value and the minimum value may be 10 ° C. or lower, preferably 8 ° C. or lower, and more preferably 6 ° C. or lower. The temperature difference can be controlled to 10 ° C. or lower by making the material of the substrate a material having high thermal conductivity, providing a cooling time after exposure, and performing an operation of cooling the substrate.

Further, the steps (2) and (4) may be performed in an air atmosphere, preferably in an atmosphere containing oxygen.

Next, as shown in (5), the photosensitive resin composition 102 in the unexposed portion is removed. In this embodiment, as an example, the black mask layer 103 is also removed at this time. As a result, a print pattern (relief image) is formed. The photosensitive resin composition 102 in the unexposed portion may be dissolved and removed by a developing solution.
