The present invention provides a coating composition comprising a binder, a rheology modifier that acts to increase the viscosity of the coating composition and a particulate component able to remove a volatile organic compound from an environment in contact with the coating composition.

A resin composition of the present invention is used for forming a second layer in an optical layer 10, contains a silicon-modified (meth) acryl resin, a urethane (meth) acrylate, and a polyfunctional (meth) acrylate, and satisfies the following condition A, in which the optical layer 10 includes a first layer (base material layer 1) containing a resin material and a visible light absorber and the second layer (protective layer 2) protecting the first layer.

Condition A: In a case where the second layer is formed on a base material, a coating film of a mixed solvent containing a petroleum-based solvent at a proportion equal to or higher than 45 wt % is formed on the second layer and left as it is, and then the mixed solvent is removed, an adherence, which is determined by a cross-cut method, of the second layer cut in the form of a lattice with respect to the base material is equal to or higher than 95%.

A curable composition comprises: a) 91 to 98.2 weight percent of: (i) at least one polymerizable compound containing at least one carbamylene group; or (ii) at least one polyurethane precursor system; and b) 0.2 to 9 weight percent of alpha alumina particles having a particle size distribution with a Dv50 of from 0.1 to 1 micron, wherein the weight percentages of a) and b) are based upon the total amount of a) and b). Cured compositions and their use in thermoforming are also disclosed.
