Document Type and Number:
WIPO Patent Application WO/2022/014558
Kind Code:
A1
Abstract:
Provided are a urethane (meth)acrylate composition and an active energy ray-curable composition with which a high hardness and excellent flexibility and weather resistance are obtained in a cured product. Also provided is a cured product exhibiting a high hardness and excellent flexibility and weather resistance. The urethane (meth)acrylate composition is: (i) a mixture containing a reaction product of the following compound (A) and the following compound (B), a reaction product of compound (A) and the following compound (C), and the following compound (D); or (ii) a mixture containing a reaction product of compound (A), compound (B), and compound (C), and compound (D). The weight ratio (B/(C + D)) of constituent units derived from compound (B) relative to the total (C + D) of compound (D) and constituent units derived from compound (C) is 0.30 to 2.00, and the weight ratio (C/(C + D)) of constituent units derived from compound (C) from among the total (C + D) of compound (D) and constituent units derived from compound (C) is 0.28 to 0.67. Compound (A): polyisocyanate
Compound (B): monofunctional (meth)acrylate having hydroxyl group
Compound (C): polyfunctional (meth)acrylate with hydroxyl group
Compound (D): polyfunctional (meth)acrylate that does not have hydroxyl group
