Definitions

  • the present invention relates to a method for preparing a heat sensitive element by spray-coating.
  • Lithography is the process of printing from specially prepared surfaces, some areas of which are capable of accepting lithographic ink, whereas other areas, when moistened with water, will not accept the ink.
  • the areas which accept ink form the printing image areas and the ink-rejecting areas form the background areas.
  • a photographic material is made imagewise receptive to oily or greasy ink in the photo-exposed (negative working) or in the non-exposed areas (positive working) on a hydrophilic background.
  • lithographic plates also called surface litho plates or planographic printing plates
  • a support that has affinity to water or obtains such affinity by chemical treatment is coated with a thin layer of a photosensitive composition.
  • Coatings for that purpose include light-sensitive polymer layers containing diazo compounds, dichromate-sensitized hydrophilic colloids and a large variety of synthetic photopolymers. Particularly diazo-sensitized systems are widely used.
  • the exposed image areas become insoluble and the unexposed areas remain soluble.
  • the plate is then developed with a suitable liquid to remove the diazonium salt or diazo resin in the unexposed areas.
  • thermoplastic polymer particles By image-wise exposure to an infrared laser, the thermoplastic polymer particles are image-wise coagulated thereby rendering the surface of the imaging element at these areas ink acceptant without any further development.
  • a disadvantage of this method is that the printing plate obtained is easily damaged since the non-printing areas may become ink accepting when some pressure is applied thereto. Moreover, under critical conditions, the lithographic performance of such a printing plate may be poor and accordingly such printing plate has little lithographic printing latitude.
  • EP-A- 514 145 discloses a heat sensitive imaging element including a coating comprising core-shell particles having a water insoluble heat softenable core component and a shell component which is soluble or swellable in aqueous alkaline medium.
  • Red or infrared laser light directed image-wise at said imaging element causes selected particles to coalesce, at least partially, to form an image and the non-coalesced particles are then selectively removed by means of an aqueous alkaline developer. Afterwards a baking step is performed.
  • the printing endurance of a so obtained printing plate is low.
  • EP-A- 599 510 discloses a heat sensitive imaging element which comprises a substrate coated with (i) a layer which comprises (1) a disperse phase comprising a water-insoluble heat softenable component A and (2) a binder or continuous phase consisting of a component B which is soluble or swellable in aqueous, preferably aqueous alkaline medium, at least one of components A and B including a reactive group or precursor therefor, such that insolubilisation of the layer occurs at elevated temperature and/or on exposure to actinic radiation, and (ii) a substance capable of strongly absorbing radiation and transferring the energy thus obtained as heat to the disperse phase so that at least partial coalescence of the coating occurs.
  • said plate After image-wise irradiation of the imaging element and developing the image-wise irradiated plate, said plate is heated and/or subjected to actinic irradiation to effect insolubilisation.
  • the printing endurance of a so obtained printing plate is low.
  • EP-A- 625 728 discloses an imaging element comprising a layer which is sensitive to UV- and IR-irradiation and which can be positive or negative working.
  • This layer comprises a resole resin, a novolac resin, a latent Bronsted acid and an IR-absorbing substance.
  • the printing results of a lithographic plate obtained by irradiating and developing said imaging element are poor.
  • US-P- 5 340 699 is almost identical with EP-A- 625 728 but discloses the method for obtaining a negative working IR-laser recording imaging element.
  • the IR-sensitive layer comprises a resole resin,a novolac resin, a latent Bronsted acid and an IR-absorbing substance.
  • the printing results of a lithographic plate obtained by irradiating and developing said imaging element are poor.
  • US-P- 4 708 925 discloses a positive working imaging element including a photosensitive composition comprising an alkali-soluble novolac resin and an onium-salt. This composition can optionally contain an IR-sensitizer. After image-wise exposing said imaging element to UV - visible - or eventually IR-radiation followed by a development step with an aqueous alkali liquid there is obtained a positive working printing plate. The printing results of a lithographic plate obtained by irradiating and developing said imaging element are poor.
  • EP-A- 800 929 discloses a heat sensitive imaging element comprising on a hydrophilic surface of a lithographic base an image forming layer comprising hydrophobic thermoplastic polymer particles dispersed in a water insoluble alkali soluble or swellable resin and a compound capable of converting light into heat, said compound being present in said image forming layer or a layer adjacent thereto, wherein said alkali swellable or soluble resin comprises phenolic hydroxy groups and/or carboxyl groups.
  • said alkali swellable or soluble resin comprises phenolic hydroxy groups and/or carboxyl groups.
  • Analogous imaging elements comprising on a hydrophilic surface of a lithographic base an image forming layer comprising hydrophobic thermoplastic polymer particles dispersed in a water or alkali soluble or swellable resin and a compound capable of converting light into heat, said compound being present in said image forming layer or a layer adjacent thereto are disclosed in e.g. EP-A-770 494, EP-A-770 495, EP-A-770 496, EP-A-770 497, EP-A-773 112, EP-A-773 113, EP-A-774 364, EP-A-800 928, EP-A-832 739, EP-A-839 648, EP-A-839 647 and EP-A-849 091.
  • poly(meth)acrylate latices are used as thermoplastic polymer particles and no specific hydrophilic resin is mentioned
  • carbon black or an IR-dye are mentioned as the compound capable of converting light into heat.
  • US-P-5 713 287 describes a direct-to-press system using a seamless cylinder onto which a curable polymer is spray coated on the press.
  • IR-dyes should be used. Carbon black causes indeed a soiling on the press when removing the unexposed areas. On the other hand when using IR-dyes the unexposed areas are not completely dissolved when developing on the press resulting in scumming.
  • the appliance of the coatings which are used at the preparation of lithographic precursor plates happens mostly with coating techniques such as dipcoating, cascade coating and curtain coating.
  • the use of spray techniques for applying lithographic layers fails usually at the attainable level of cosmetic quality of the end product.
  • the conditions for high qualitative lithographic materials thermal printing plates well or not processable on press) whereat high resolution, sensitivity and reproducing characteristics are required, are very high with relation with the cosmetic quality of said printing plate.
  • This cosmetic quality can be translated as the presence of lines, the general evenness and the presence of a mottle pattern. This mottle pattern appears at the slighest presence clearly in the printing process of large screen planes.
  • a line is sprayed without transverse movement of the spray head.
  • a well swelling receiving layer comprising gelatin, polyvinylpyrrolidone and polyethylene glycol ( Agfajet Photograde paper HP Glossy 165TM, commercially available from Agfa-Gevaert) was used. This results in an immediate freezing of the spray pattern without the possibility of transverse flowing of the spray solution over the receiving surface.
  • the density profile of the line is measured.
  • the width at half height of this profile is divided by the total height (the maximum density) of the profile. This value is referred as profile value (P).
  • This profile value is determined by the air pressure of the spraying head, by the flow rate of the spraying head and by the nature of the receiving surface.
  • This value lies preferably between 50 and 220 mm although this value has to be considered in the context of the given equation.
  • the surface tension of the spray solution lies preferably between 22 mN/m and 60 mN/m.
  • the distance between the spray head and the receiving member lies preferably between 25 and 100 mm.
  • the spray solution is preferably an aqueous solution, which may comprises surfactants, preferably fluorosurfactants.
  • the viscosity of the spraying solution is preferably at least 1.5 mPa.s.
  • the receiving surface can be a drum with a hydrophilic surface, which can be incorporated in a printing machine.
  • the receiving surface can be a lithographic surface mounted on a drum.
  • a preferred spraying solution is a dispersion of hydrophobic thermoplastic polymer particles in a hydrophilic binder.
  • Said solution preferably includes thermoplastic particles of a homopolymer or a copolymer of styrene and a hydrophilic polymer containing carboxyl groups, and further a compound capable of converting light into heat.
  • Such solutions suitable for spraying heat sensitive imaging elements are described with their exposure and development in EP-A- 98 200 187.
  • the receiving element is a lithographic base with a hydrophilic support, namely an anodized roughened aluminum support.
  • the imaging element obtained by spraying the spray solution on the receiving element can after exposure to an IR-laser be developed by rinsing the element with an aqueous solution.
  • the exposed imaging element is mounted directly on the press.
  • a 2.61 wt solution in water was prepared by mixing polystyrene latex, dye I and a hydrophilic binder. After spraying and drying, the resulting layer contained 75% W/W of the polystyrene latex, 10% of the dye A and 15%W/W of Glascol E 15TM.

  • the structure of Dye I is as follows.
  • a 0.30 mm thick aluminum foil was degreased by immersing the foil in an aqueous solution containing 5 g/l of sodium hydroxide at 50°C and rinsed with demineralized water.
