ABSTRACT OF THE DISCLOSURE A coating composition comprising (a) a monomer mixture of 30 to 90% by weight of at least one poly(meth)acrylate of mono or polypentaerythritol having at least three (meth)acryloyloxy groups in one molecule of the formula (I) Image (I) wherein at least three of X11 X12- X13- X22 X23. . . Xn2, Xn3 and X14 are CH2=CH-COO- groups and the rest of them are -OH groups n is an integer of 1 to 5 and R represents hydrogen or a methyl groups, and 70 to 10? by weight of at least one monofunctional acrylate or methacrylate having at least one ether bond in one molecule a boiling point above 150°C under normal pressure and a viscosity below 20 centipoises at 20°C; (b) 0.01 to 10 parts by weight of a photosensitizing agent per 100 parts by weight of a said monomer mixture; (c) 0.0001 to 2.0 parts by weight per 100 parts by weight of said monomer mixture of at least one silicon type surface active agent of the formula (II) or (III): Image (II) wherein X is Image m and n are positive integers being smaller than 200 and x and y represent 0 or positive intergers being smaller than 200 and satisfy the formula Image 10 and R1 represents -H or an alkyl, acyl or aryl group having 1 to 6 carbon atoms or Image (III) wherein Y is Image , m and n represent positive intergers being smaller than 200, x and y represent 0 or positive intergers being smaller than 200 and z represents 0 or a positive integer of 1 to 5 and satisfy the formula Image , R2 represents Image , -H or an alkyl, acyl or aryl group having 1 to 6 carbon atoms, and R3 represents -H or an alkyl,acyl or aryl group having 1 to 6 carbon atoms; and (d) 10 to 1900 parts by weight per 100 parts by weight of said monomer mixture of at least one organic solvent capable of forming a uniform solution upon mixing with said monomer mixture. A process of coating surfaces with these coating compositions is also disclosed.
