Abstract
Abstract A storage-stable lacquer resin which can be baked without yellowing at a low baking temperature, and is based on an alkyd resin, acrylic resin or epoxy resin, is obtained by reacting the resin with a bis- or tris-alkoxyalkylamino-s-triazine which has been obtained by heating a triazine derivative of the general formula: ##STR1## wherein X is an alkyl group having 1 to 4 carbon atoms, a phenyl group or the group ##STR2## and each of R and R' is an alkyl group radical having up to six carbon atoms, at 100° to 200° C. up to a weight loss of 3 to 25%, preferably 5 to 15%.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
In a process for the preparation of a storage-stable lacquer resin which can be baked without yellowing and which has a high reactivity, a good solubility in organic solvents and a low viscosity in solution and is based on the reaction product of an alkyd resin, acrylic resin or epoxy resin with a bis- or tris-alkoxyalkylamino-s-triazine, the improvement which comprises using a bis- or tris-alkoxyalkylamino-s-triazine which has been obtained from a triazine derivative of the general formula: ##STR5## wherein X is an alkyl group having one to four carbon atoms, a phenyl group or the group ##STR6## and each of R and R' is an unbranched or branched alkyl group having up to six carbon atoms, by heating for a period of 3 to 300 minutes at a temperature of 100° to 200° C., up to a weight loss of 3% to 25%, relative to the dry weight of the triazine starting compound.

Claim 3
Dependent Claim
24 words
A process according to claim 1, in which the triazine derivative of formula I is heated to a weight loss of 5 to 15%.
Claim 4
Dependent Claim
23 words
A process according to claim 1, in which the heating of the triazine derivative of formula I is carried out in a solvent.
