Method of bonding with adhesive composition containing a thiocarboxylic acid compound
First Claim
1. A method of bonding a metal or alloy to another material, comprising:
- (i) applying an adhesive composition to said metal or alloy to obtain an adhesive coated metal or alloy; and
(ii) contacting said another material with said adhesive coated metal;
wherein said adhesive composition comprises a polymerizable thiocarboxylic acid or derivative thereof of the formula;
##STR47## wherein R4 is hydrogen or methyl;
R6 is an organic group of 1 to 40 carbon atoms which can contain --OH, --C═
N, --NH2, --SO3 H, halogen, --COOH, --CSSH or --COSH;
Y is --COO--, --OOC--, --CONH--, --COS--, --SOC--, --S-- or ##STR48## with the provision that when Y is --COO--, --OOC--, --CONH--, --COS--, --SOC-- or --S--, n is 1, and when Y is ##STR49## n is 0 or 1.

Abstract
An adhesive composition comprising a polymerizable thiocarboxylic acid or a derivative thereof of the general formula ##STR1## wherein X1 is an oxygen atom or a sulfur atom and where X1 is an oxygen atom, R1 is an organic group containing at least one olefinic double bond and R2 is a mercapto group, and where X1 is a sulfur atom, R1 is an organic group and R2 is a mercapto group, a halogen atom, --OR3, or --SR3, where R3 is a monovalent organic group, and at least one of R1 and R3 has at least one olefinic double bond, are useful as primers or adhesives and provide a water-resistant, high-strength bond to noble metal adherends which are used in dental and other applications.
