The configuration of the method for producing a molded article with a picture having a tuned embossing pattern according to the present invention will be described below with reference to the drawings.

The first step of the method for producing a molded article with a tuned embossing pattern according to the present invention is, for example, a transfer sheet indicated by reference numeral 20 in FIG. 2, that is, a first printing layer 21 having liquid repellency. And a second printing layer 22 having no liquid repellency, two types of printing layers are directly formed on a transfer sheet substrate 23 made of a water-soluble or water-swellable film.
20 to the transfer sheet base material 23 in the transfer sheet
After being floated on the water surface with the surface facing downward, an activator containing a solvent that dissolves the first printing layer 21 and the second printing layer 22 in the transfer sheet 20 is added to the first printing layer. Applied to the printed layer surface of 21 and the second printed layer 22, or
In the transfer sheet 20, the first print layer 21 and the second print layer 21
After applying the activator to the print layer surface of the print layer 22 of,
The transfer sheet 20 coated with this activator is floated on the water surface so that the surface of the transfer sheet base material 23 of the transfer sheet 20 is the lower surface, and the printing layer 21 of the transfer sheet 20 is formed. , 22 are in a state of being coated with an activator, and also forming a state of being floated on the water surface.

The transfer sheet 20 used in the first step is a transfer sheet base material 23 made of a water-soluble or water-swellable film, and a liquid-repellent substance directly formed on the transfer sheet base material 23. First printing layer 21 containing printing ink containing
And two types of printing layers, that is, the second printing layer 22 made of printing ink containing no liquid repellent substance, are essential components.

Preferable specific examples of the transfer sheet base material composed of a water-soluble or water-swellable film include polyvinyl alcohol resin, dextrin, gelatin, glue, casein, shellac, gum arabic, starch, protein, polyacrylic acid amide. , Sodium polyacrylate, polyvinyl methyl ether, copolymer of methyl vinyl ether and maleic anhydride, copolymer of vinyl acetate and itaconic acid, polyvinylpyrrolidone, or cellulose, acetyl cellulose, acetyl butyl cellulose, carboxymethyl cellulose, methyl cellulose, hydroxy Examples of the film include a cellulose derivative such as ethyl cellulose and a resin such as sodium alginate alone or a mixed resin having a thickness of about 10 to 100 μm. The polyvinyl alcohol resin film, the degree of polymerization, the degree of saponification, by changing various conditions such as the addition of additives such as starch, the mechanical strength required during printing, moisture resistance during handling, float on water It is possible to control the speed of softening due to water absorption from, the time required for spreading or diffusing, the ease of deformation during transfer, and the like. An example of a more preferable film containing polyvinyl alcohol (PVA) resin as a main component is a composition of PVA …… 80% high molecular water-soluble resin …… 15% starch …… 5% and equilibrium water content of about 3%. It is a thing.

In addition, the water when floating the transfer sheet 20 is
The temperature is adjusted to an appropriate temperature depending on the properties of the water-soluble or water-swellable film as the transfer sheet substrate 23 in 20. For example, as a water-soluble film, a starch-based film (trade name:
When using a wafer, the water temperature is preferably about 40 to 50 ° C, and about 2 to 4% of amylase or the like is added in advance in order to accelerate the dissolution at the time of removing the film. preferable.

As the ink composition for forming the printing layer on the surface of the transfer sheet substrate, those known per se can be used.
For example, various kinds of fats and oils such as linseed oil, soybean oil and synthetic drying oil, cellulose derivatives such as ethyl cellulose, ethyl hydroxyethyl cellulose cellulose acetate propionate, nitrocellulose and cellulose acetate, styrene resins such as polystyrene and poly α-methylstyrene. And styrene copolymer resin, homopolymer or copolymer resin of acrylic or methacrylic resin such as polymethylmethacrylate, polyethylmethacrylate, polybutylmethacrylate, polyethylacrylate, polybutylacrylate, rosin, rosin-modified maleic acid resin , Rosin-modified phenol resin, rosin ester resin such as polymerized rosin, polyvinyl acetate resin, coumarone resin, vinyltoluene resin, vinyl chloride resin, polyester resin, butyral resin, polyamide resin, chloride A vehicle having at least one selected from Nyl-vinyl acetate copolymer resin, polyvinylidene chloride, melamine resin, silicone resin, chlorinated rubber, rubber derivatives of cyclized rubber, glue, casein, dextrin, zein, etc. Can be used. Although this ink composition is usually colored with a dye or pigment,
In some cases, it may be colorless without coloring. Further, it may contain a pearl pigment, a metal powder or the like for the purpose of producing a special effect. In order to form the printing layer as an union of independent dots, it is preferable to use gravure printing, gravure offset printing, screen printing, or the like, which is performed using a printing plate prepared according to the shape of each point described above. Just do it. Further, when forming this printing layer, the ink constituting each point flows in an undried state and the points do not connect to each other, so that the viscosity is higher than that in normal printing and the drying speed is fast. It is better to use ink. Further, it is preferable to use a plate having a large amount of ink transfer in order to obtain a desired thickness of the printing layer, but if the amount of ink transfer is excessive, dots may still be connected. Taking these points into consideration, taking the gravure printing method as an example, the plate depth is about 20 μm to 50 μm, and the cell width / bank width = 5 /
It is preferable to form the printing layer by using a gravure printing plate of about 2 and an ink composition in which the outflow required time when using Zahn Cup No. 4 is about 9 to 15 seconds.

Furthermore, the second printing layer having no liquid repellency is applied to the conventionally known ink composition, specifically, to the repellency described in 1) to 7) in the section of [Prior Art] above.

The first printed layer having liquid repellency and the second printed layer having no liquid repellency can be distinguished also by the difference in the content of the liquid repellent substance.

The activator applied to the printing surfaces of the first print layer 21 and the second print layer 22 in the transfer sheet 20 contains a solvent having a property of dissolving the print layer, The operation of transferring the first printing layer 21 and the second printing layer 22 of the sheet to the surface of the molded body substrate to be painted does not evaporate until it is completed on the water surface, and the molded body is also formed.

It is easy and the application means is not limited, and since the ink holding time of the printing layer on the transfer sheet is long, there is an advantage that the transfer process can take a long time. The activator may be applied by gravure coating, offset gravure coating, roll coating, bar coating, spray coating, ultrasonic coating, etc., and the amount of activator applied is about 1 to 50 g / m ² .

In order to float the transfer sheet on the water surface, it is possible to float the sheet-like materials one by one, or the roll-shaped material can be continuously floated on the water surface while flowing water in one direction. In this step, the transfer sheet base material 23 of the transfer sheet 20 is floated on the water surface so that the surface thereof faces downward, that is, the printing layers 21 and 22 face upward, and at this time, the transfer is performed.

In order to remove the water-soluble or water-swellable film 23 in the transfer sheet 20, it is the most efficient and preferable method to shower-transfer the transferred material with water,
As a result, the attached film 23 is completely removed, and the stains generated during the transfer are also washed. At this time, the water temperature varies depending on the material of the water-soluble film used and the like, but generally 15 to 60 ° C. is appropriate, and the washing time is about 1 to 10 minutes.
