Abstract
A radiation curable coating comprising: (i) at least one radiation polymerizable reactant; (ii) at least one initiator for initiating cure; (iii) at least one wax; wherein the wax is present in an amount sufficient to reduce the 60° gloss of the cured coating to a gloss level less than 40 when the coating is cured by exposure to radiation in the presence of oxygen to provide a dry film thickness of 1.0±0.1 mil.
Claims41
A flexible sheet having a first side and a second side opposite to the first side, wherein the second side is coated with an adhesive material, and wherein said first side is coated with a cured film;
- wherein the cured film is obtained by a process which comprises:
- (i) applying to said first side of the substrate a radiation curable liquid coating composition comprising:
- (a) at least one radiation polymerizable reactant;
- (b) at least one initiator for initiating cure;
- (c) at least one wax;
- and
- (ii) exposing the applied coating composition to radiation in the presence of oxygen until cured;
- wherein the oxygen is present in an amount sufficient to inhibit, but not prevent, the surface cure of the coating.
A substrate having adhesively applied to at least one surface thereof a flexible sheet, wherein said flexible sheet has a first side and a second side opposite to the first side, and wherein the second side is coated with an adhesive material which is applied to said substrate surface, and wherein said first side is coated with a cured film;
- wherein the cured film is obtained by a process which comprises:
- (i) applying to said first side of the substrate a radiation curable liquid coating composition comprising:
- (a) at least one radiation polymerizable reactant;
- (b) at least one initiator for initiating cure;
- (c) at least one wax;
- and
- (ii) exposing the applied coating composition to radiation in the presence of oxygen until cured;
- wherein the oxygen is present in an amount sufficient to inhibit, but not prevent, the surface cure of the coating.
