Abstract
A low temperature curing high solid coating composition which comprises: (I) acrylic resin having a glass transition temperature of 20.degree. to -50.degree. C. and a hydroxyl value of 40 to 280, which is obtained by copolymerizing the monomer mixture comprising (a) acrylic ester and/or methacrylic ester, and if necessary, (b) acrylic acid or methacrylic acid, (II) amino-formaldehyde resin which is etherified with a monohydric alcohol, (III) an acid catalyst, and if necessary, (IV) cellulose derivatives and/or (V) metallic coordination compounds of titanium, zirconium and/or aluminium. The coating composition of the invention is characterized in that it has a high solid content and is cured at a low temperature and the obtained coating film has quite excellent properties of durability, hardness and chemical resistance.
