A method of profile lapping adhesion which comprises:

Photocurable adhesive of hydroxy-polyesterurethane acrylate, monomer and

A solid resin composition useful for coating and bonding, which comprises a carboxyl-modified product of a hydrolyzed ethylene/vinyl acetate copolymer, a carboxyl-terminated saturated polyester resin and a solid epoxy resin with an epoxy equivalent of 80 to 400, each of the component being blended at a specified ratio. The composition, when baked, affords tough coating films or adhesive layers with markedly improved heat and impact resistances in addition to high hardness, strong adherence and high chemical resistance.

Solid resin composition

A powdery coating composition comprising (A) a carboxyl-modified product of a hydrolyzed polymer obtained by hydrolyzing a copolymer derived from a vinyl ester of a saturated monocarboxylic acid and a vinyl monomer polymerizable therewith and (B) a compound having not less than two epoxy groups in the molecule offers extremely tough coating films which are resistant to chemicals, water and salt spray.

Powdery coating composition

A polyurethane based composition for powder coating uses, which comprises a combination of an organic polyisocyanate compound and a hydroxyl-containing compound, the hydroxyl-containing compound being

Polyurethane composition for powder coating

A composition for powder coating which comprises a carboxyl-containing polymer of not lower than 40.degree. C. in softening point prepared by reacting a dicarboxylic acid anhydride with a hydroxyl-containing polymer obtained by saponifying a copolymer from a vinyl ester of a saturated monocarboxylic acid and a copolymerizable vinyl monomer, and a compound having two or more oxazaline rings in the molecule, from which are obtained coating layers with toughness and flexibility useful for coating glass bottles, etc.

Composition for powder coating

A process for producing a polymer having crosslinked structure, which comprises reacting a polymer having in the molecule a partial structure of the formula: ##STR1## with an oxazoline derivative of the general formula: ##STR2## wherein n is an integer of 1 to 4; R is an n-valent aromatic hydrocarbon radical; R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are respectively the same or different hydrogen or alkyls having not more than 3 carbon atoms. The polymer shows an excellent adherence, and is of great industrial value as coatings, adhesives and molding materials with by far improved heat and solvent resistance.
