Abstract
Disclosed is a composition for forming a polyurethane film with improved reaction stability, comprising an OH group-containing polymer; an isocyanate-based compound as a curing agent; and an alicyclic urea diol compound having two urea groups and an OH group at two terminals, and a polyurethane film with improved self-healable property from tear, derived from the composition.
Claims7
A composition for forming a polyurethane film, comprising:
- an OH group-containing polymer;
- an isocyanate-based compound as a curing agent;
- and an alicyclic urea diol compound having two urea groups and an OH group at two terminals, wherein the alicyclic urea diol compound is included in an amount of 0.1 to 30 parts by weight based on 100 parts by weight of the OH group-containing polymer,
- wherein the OH group-containing polymer comprises a polymer comprising a repeat unit derived from an OH group-containing acrylate-based monomer, an OH group-containing methacrylate-based monomer, and an OH group-containing styrene-based monomer.
