Abstract
The invention provides an active energy ray-curable composition which can be prepared from easily available raw materials, which has excellent coating properties, and which forms, when cured, a coat having a good adhesion to a polyolefin, and a method for forming the coat using the composition. That is, the invention is an active energy ray-curable composition containing a reaction product between an isocyanate compound having an isocyanate group bound to a non-aromatic hydrocarbon ring and a (meth)acryl compound having a (meth)acryloyl group and being capable of reacting with an isocyanate group, and a method for forming a coat using the composition.
Claims23
A laminate comprising a polyolefin substrate having formed thereon a layer comprising an active energy ray-curable composition which comprises a reaction product between an isocyanate compound having an isocyanate group bound to a non-aromatic hydrocarbon ring and a (meth)acryl compound having a (meth)acryloyl group and being capable of reacting with the isocyanate group.
A method of adhering polyolefin, which comprises using an active energy ray-curable composition which comprises a reaction product between an isocyanate compound having an isocyanate group bound to a non-aromatic hydrocarbon ring and a (meth)acryl compound having a (meth)acryloyl group and being capable of reacting with the isocyanate group.
A process for producing a substrate with a coat, which comprises forming on the substrate a coat layer comprising an active energy ray-curable composition comprising a reaction product between an isocyanate compound having a melting point of 40° C. or higher and a (meth)acryl compound having a (meth)acryloyl group and being capable of reacting with the isocyanate group, which product has a softening point of 40° C. or higher, conducting fabrication, then curing the active energy ray-curable composition.
