  • Patent number: 6340504
    Abstract: A coated plastic or high pressure laminated article and a process for making same includes coating a plastic or high pressure laminated substrate with a radiation curable top coat which may include ultraviolet inhibitors therein. The radiation curable top coat is subjected to a curing step which includes curing with either an electron beam, ultraviolet radiation or a combination thereof. The resulting article is a coated article which is comprised of a substrate coated with a radiation cured coating having an outer surface susceptible for receiving a sublimatable ink diffused therein.

  • Patent number: 6124401
    Abstract: This invention provides for a coating composition comprising: (A) at least one polymeric material selected from (i) at least one homopolymer of ethylene having a melt index of at least about 220 grams per ten minutes as determined by ASTM D1238, condition 190/2.16, or (ii) at least one copolymer of ethylene and a second ethylenically unsaturated monomer having a melt index of at least about 20 grams per ten minutes as determined by ASTM D1238, condition 190/2.16, or (iii) at least one thermoplastic acrylic homopolymer or copolymer having a glass transition temperature (Tg) of greater than 0.degree. C. but less than 110.degree. C., or (iv) a mixture of (i), (ii) and/or (iii); and (B) at least one thermoplastic polymeric material different than (A) having a melting point in the range of about 80.degree. C. to about 130.degree. C.
