Abstract:
1. A composition for use as a base coat or varnish, having a viscosity of 25° C. on a Brookfield RVDT digital viscometer at 5 r.p.m. using a No. 6 spindle of between 40 and 1000 poise, and a viscosity under higher shear, as measured on the Rotothinner (supplied by Sheen Instruments) between 6 and 65 poise, the composition comprising: (i) from 10 to 80% by weight of the composition of one or more ethylenically unsaturated monomers, oligomers or prepolymers that are capable of being photopolymerized; (ii) from 0.5 to 20% by weight of the composition of a photoinitiator that is capable of initiating the polymerization of the ethylenically unsaturated monomers (i) when irradiated with ultra-violet light; (iii) from 0.5 to 50% by weight of the composition of an inorganic transfer agent; and (iv) between 0.1 and 6% by weight of the composition of a heavy metal salt.
