Abstract
The invention relates to a resin composition exhibiting excellent coatability and capable of forming coatings with high hardness, superior scratch resistance, low curling properties, superb adhesion, excellent transparency, and superior coating surface appearance without a wavy striation, streaks, unevenness of coatings, cissing, and the like, as well as cured products made from the resin composition.
Claims22
