Abstract

A near infrared rays-curing putty composition containing (A) a polymerizable ethylenically unsaturated group-containing resin, (B) a polymerizable ethylenically unsaturated compound and (C) a near infrared rays polymerization initiator, said near infrared rays polymerization initiator (C) being a near infrared rays-absorbing cationic dye and a resin powder consisting of gelation polymer fine particles.

Claims

1. A near infrared rays-curing putty composition comprising:

(A) a resin containing at least one polymerizable ethylenically unsaturated group,

(B) a polymerizable unsaturated compound comprising monomers or oligomers containing at least one ethylenically unsaturated group,

(C) a near infrared rays polymerization initiator, said near infrared rays polymerization initiator (C) being a near infrared rays-absorbing cationic dye, and

(D) a resin powder consisting of gelation polymer fine particles obtained by emulsion polymerization, said gelation polymer fine particles being contained in an amount of 1 to 100 parts by weight per 100 parts by weight of a total solid content in the resin (A) and compound (B).

2. A composition as claimed in claim 1, wherein the polymerizable unsaturated group-containing resin (A) is selected from the group consisting of an unsaturated polyester resin having a number average molecular weight of 500 to 10,000, an unsaturated epoxy resin having a number average molecular weight of 300 to 10,000, and an unsaturated acrylic resin having a number average molecular weight of 2,000 to 50,000.

3. A composition as claimed in claim 2, wherein the unsaturated polyester resin has an allyl group.

4. A composition as claimed in claim 1, wherein a weight ratio of the resin (A) and the compound (B) is in the range of 90/10 to 10/90.

5. A composition as claimed in claim 1, wherein the initiator (C) is used in an amount of 0.01 to 10% by weight based on a total amount of the resin (A) and the compound (B).

6. A composition as claimed in claim 1, wherein said composition further contains a cellulose derivative.

7. A composition as claimed in claim 1, wherein said composition further contains an adhesion promoting phosphate group-containing compound.
