PURPOSE:To provide a polymerizable resin suitable as an impregnation material of a releasing paper for the production of artificial leather, by reacting a specific melamine compound, a polyhydric alcohol, an acrylamide compound and a modified polysiloxane. CONSTITUTION:The objective polymerizable resin having ethylenic unsaturated bond is prepared by reacting (A) 1mol of a melamine compound of formula I [R' is H or 1-4C alkyl; R is CH3, phenyl, -N(CH2OR')2, or organic group of formula II (Y is -CH2OR' or H)] with (B) 1.5-4 equivalent (one OH group is 1 equivalent) of a polyhydric alcohol having a molecular weight of 62-500, (C) 1-4.5mol of (alpha-lower alkyl-substituted) acrylamide and (D) 0.1-50wt%, based on A+B+C, of a modified polysiloxane having one or more -SH, -OH, -CONH2 and/or -COOH groups in the molecule. |
