Abstract

PURPOSE:To enhance resistance to chemicals and solvents in the cleaning of a screen and resistance to wear in the squeegeeing of the screen, by a method wherein a strong resin protective film made of a composition of an electron ray-curing or ultraviolet-curing acrylate resin or unsaturated polyester resin is provided on the both faces of cross portions of a gauze and a photosensitive film corresponding to non-image areas. CONSTITUTION:A photosensitive film 4 is uniformly formed by coating from one side of a gauze 2. The photosensitive film 4 is formed not only on the coating face side of the gauze 2 but also on the reverse thereof slightly. After the photosensitive film 4 is coated and dried, pattern elements 5 of an original picture are so formed as to be in close contact with the surface of the photosensitive film 4 to be exposed by an ultraviolet lamp 6. After the exposure, the photosensitive film is developed so that the unexposed portions are removed. On the gauze 2, image areas 7 and non-image areas 8 are formed. The photosensitive film is dried, thereafter being coated with a composition 9 of an electron ray-curing or ultraviolet-curing acrylate resin or unsaturated polyester resin on the both faces thereof. After the coating, the resin composition of the image areas 7 is removed; in this case, the resin applied only to the image areas 7 is partially allowed to remain on cross portions 10 of the gauze 2. The resin composition 9 coated on the both faces of a screen 1 is irradiated with an electron rays source or ultraviolet light source 11 for curing.

(b) Conventional techniques and their problems Conventionally, printing screens for textile printing or printing using gauze have been used to protect the formed image and non-image areas during image formation on a photosensitive film coated on the gauze. A resin coating is applied. Conventionally, the resin used for the purpose of protecting the image area of a printing screen is a two-component reaction-curing polyurethane resin coating that utilizes a curing reaction between a polyol component having a hydroxyl group and an isocyanate.

However, since this polyurethane resin paint contains a large amount of organic solvent, it is necessary to volatilize the solvent after application. Furthermore, since the curing reaction proceeds following the solvent volatilization treatment, several tens of hours of drying time are required, which is extremely unreasonable in terms of productivity and workability. On the other hand, forced curing methods using hot air drying or the addition of catalysts have been studied, but the fundamental problem with such forced curing methods is that the shrinkage of the coating is large, which adversely affects the dimensional accuracy of the screen. It had some drawbacks. Further, the protective coating film for the printing screen is required to be flexible, and in response to this requirement, a soft polyurethane grease-resistant paint is used. However, this soft polyurethane resin has insufficient chemical and solvent resistance during screen cleaning.
In addition, the abrasion resistance during scaging was insufficient. Furthermore, since this flexible polyurethane resin is a two-component reactive resin, even after adding the curing agent, the curing will proceed as soon as the two components are mixed, and at the beginning and end of the work, even during the work. It has the disadvantage that it is impossible to keep its viscosity constant, and it is extremely difficult to apply it continuously for a long time.
