Abstract
Official abstract text for this publication.
The purpose of the present invention is to provide a transfer sheet capable of providing hard coat properties and excellent weather resistance to a resin molded article such as organic glass. The transfer sheet has, in order, a base material film for mold release, a hard coat layer, a primer layer, and an adhesive layer. The weather resistance and adhesiveness of the hard coat layer and the primer layer are improved and hard coat properties and excellent weather resistance can be provided to a resin molded article being the transfer object, as a result of: the hard coat layer being formed from a cured product of a resin composition including a curable resin; and the primer layer being formed from a binder resin including a polyurethane having a mass-average molecular weight of 40,000-100,000 and including 1-30% by mass of an acrylic component.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hard coated article comprising: at least a hard coat layer, a primer layer, an adhesive layer, and a resin molded article in this order, wherein the hard coat layer is formed of a cured product of a resin composition containing a curable resin, and the primer layer is formed of a binder resin containing polyurethane having a mass average molecular weight of 50,000 to 80,000; wherein the polyurethane is a copolymer consisting of an acrylic component and a urethane component with 5 to 20% by mass of the acrylic component, and wherein the urethane component is a polycarbonate-based urethane. 2. The hard coated article according to claim 1 , wherein the curable resin is an ionizing radiation curable resin. 3. The hard coated article according to claim 1 , wherein the curable resin is a combination of (i) a tri- or more functional ionizing radiation curable resin and (ii) a bifunctional (meth)acrylate monomer. 4. The hard coated article according to claim 1 , wherein the adhesive layer contains a heat-sensitive adhesive resin or a pressure-sensitive adhesive resin. 5. The hard coated article according to claim 1 , further comprising a colored layer provided in part of at least one position of on a surface of the hard coat layer, between the layer and the adhesive layer, or between the adhesive layer and the resin molded article.
