PURPOSE:To improve the water developing, the water resisting and the screen adhesive properties of the title composition by incorporating an inner cross- linking type acrylic resin emulsion in the component of the resin composition as a synthetic resin emulsion using especially PVA as an emulsifier. CONSTITUTION:The resin composition is mainly composed of three components comprising the aqueous emulsion of an inner crosslinking type acrylic resin which has >=65wt.% of a trichlene insoluble matter, and is obtd. by subjecting an acrylic monomer and a monomer having two or more of polymerizable unsatd. groups to an emulsion polymerization in the presence of polyvinyl alcohol (PVA) having a degree of polymerization of <=1,500, the polyvinyl alcohol and/or its derivative and a photosensitive agent. And, the monomer having two or more of the polymerizable unsatd. groups is composed of the monomer having two or more of allyl groups. Thus, the characteristics such as the water developing, the water resisting and the screen adhesive properties of the resin composition are sufficiently satisfied. |
