  • Water-absorbent coating compositions
    Patent number: 4977208
    Abstract: (A) Water-absorbent coating compositions comprising (1) a nonaqueous dispersion of a resin, or a solution of a resin, and (2) a water-in-oil type emulsion of a water-swellable polymer with an average particle size not greater than 10 .mu.m; and a process for coating the same which uses a proper primer. (B) Water-absorbent coating compositions which comprise 100 parts by weight (on dry basis) of a resinous solution and 10 to 150 parts by weight (on solid basis) of a dehydrated water-in-oil type emulsion of a water-swellable polymer with an average particle size not greater than 10 .mu.m and which gives coated film with an elongation not lower than 30%.
