Protective coating material

A protective coating material free of non-reactive solvents which, prior to application to a substrate to be coated, consists essentially of

• (A) (meth)acrylate derivatives of the following formulas 1, 2, 3, 4 and 5 within the following ranges of a, b, c, d and e % by weight, respectively:
• 5.ltoreq.a.ltoreq.80, 0.ltoreq.b.ltoreq.30, 0.ltoreq.c.ltoreq.30, 5.ltoreq.d.ltoreq.50,
• 0.ltoreq.e.ltoreq.50, provided that a+b+c+d+e=100, ##STR9## wherein each of R.sub.1 to R.sub.3 is H or CH.sub.3, and R.sub.4 is CH.sub.2 CH.sub.3 or CH.sub.2 OH, ##STR10## wherein each of R.sub.5 to R.sub.8 is H or CH.sub.3, ##STR11## wherein each of R.sub.9 to R.sub.14 is H or CH.sub.3
• CH.sub.2 .dbd.C(R.sub.15)COO(CH.sub.2).sub.n OCOC(R.sub.16).dbd.CH.sub.2 4
• where each of R.sub.15 and R.sub.16 is H or CH.sub.3, and n is an integer of from 2 to 10 ##STR12## wherein R.sub.17 is H or CH.sub.3 ;
• (B) a photoDolymerization initiator in an amount of from 0.1 to 10% by weight relative to total weight of said (meth) acrylate derivatives (A), and
• (C) a leveling agent in an amount of from 0.005 to 3% by weight relative to total weight of said (meth)acrylate derivative (A).
