<p>PURPOSE:The titled composition having improved adhesion and water resistance free from an organic solvent, comprising a hydrosol composition obtained by adding an alkali and water to a mixture consisting of a photo-crosslinkable copolymer prepared from a specific acrylic copolymer and a sensitizer. CONSTITUTION:The desired composition comprising a hydrosol composition having 0.01-0.1mu average particle diameter, obtained by adding an alkali and water to a mixture of a photo-crosslinkable copolymer obtained by reacting (A) an acrylic copolymer having 1X10<4>-1X10<6> weight-average molecular weight having (i) 98-50wt% main monomer containing (meth)acrylic acid ester as a main component, and (ii) 2-20wt% copolymerizable unsaturated monomer with an acidic group of carboxyl group or sulfonic group, with (B) a compound containing a functional group and (meth)acryloyl group to be reacted with the active group and an active hydrogen in such a way that the acidic group in the component A remains after the reaction, and a photosensitizer.</p> |
