  • Patent number: 6660337
    Abstract: A decorative film for use in plastics molding, said decorative film being a laminate film prepared by outwardly and successively laminating a polyolefin film layer, a primer layer, optionally a topcoating layer and a releasable layer, said primer layer being a coating film formed from an isocyanate-curing type resin composition containing (A) a hydroxyl group-containing resin having a hydroxyl number of 30 to 200 KOH mg/g on an average and a weight average molecular weight of 1000 to 80000, (B) a polyolefin based resin and (C) a (blocked)polyisocyanate compound in such mixing amounts that a number of the isocyanate group in the component (C) is in the range of 0.1 to 0.9 per one hydroxyl group in the component (A) and that the component (B) is in the range of 1 to 90% by weight based on a total weight of the components (A), (B) and (C), and having a static glass transition temperature of 20 to 70° C., an elongation of 10% or more and a tensile strength of 0.

  • Patent number: 5880187
    Abstract: The present invention relates to a top coating composition having:(A) A hydroxyl-containing vinyl resin containing 40 to 90 wt. % of an aromatic hydrocarbon ring-containing vinyl monomer as a monomer component, optionally in combination with (B) a hydroxyl-containing polyester resin,(C) hexamethoxymethylmelamine and/or an etherified melamine resin obtained by substituting a part or the whole of the methoxy groups in hexamethoxymethylmelamine by an alkoxy group having at least 4 carbon atoms,(D) a particulate polymer having an average particle diameter of 0.01 to 1 .mu.m, and(E) a polysiloxane compound represented by the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are the same or different and each represent a C.sub.1-10 alkyl group, a C.sub.1-10 alkoxy group or a hydroxyl group, R.sub.5 and R.sub.6 are the same or different and each represent C.sub.1-10 alkyl group or a hydrogen atom, and n is an integer of 10 to 1,000.
