Coating compositions comprising an acrylic solution polymer having a molecular weight of about 30,000 to 250,000 and a Tg above 65.degree. F., a solvent therefor, and a compatible acrylic polymer having a Tg less than -20.degree. F., which is soluble in the same solvent, coated substrates, and especially coated impact-modified acrylic sheets having improved resistance to impact.
本发明涉及一种涂层组合物,包括分子量在30,000至250,000之间且玻璃化转变温度高于65°F的丙烯酸解聚物、其溶剂以及一种与其溶于相同溶剂的Tg小于-20°F的相容性丙烯酸聚合物,所涂覆的基材,特别是涂层改性丙烯酸板材,其具有改善的抗冲击性。
