Abstract
Abstract A surface modifier for a powdery or granular substance having a hydrophilic surface is provided. The surface modifier comprises an aluminum chelate compound of the formula (I): ##STR1## wherein R 1 is selected from hydrogen and C1-6 alkyl, R 2 is selected from methyl and phenyl, R 3 is selected from R 4 --, R 5 O-- and R 6 NH--, A is selected from R 7 O--, R 8 COO--, R 9 SO 3 --, R 10 OSO 3 --, ##STR2## R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 and R 13 are C1-22 alkyl or C3-22 alkenyl, aryl, aralkyl or alkylarly, R 3 may be the same as or different from R 7 , R 8 , R 9 , R 10 , R 11 , R 12 and R 13 , with the proviso that at least one of R 3 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 , and R 13 is a substituent having at least 8 carbon atoms of a polymerizable alkenyl group, and m=0.5 to 2.7, n=0.3 to 2.5 and m+n=0.8 to 3.

Claim 1
Independent Claim
232 words
A surface modifier for a powdery or granular substance having a hydrophilic surface, which comprises at least one aluminum chelate compound represented by the following general formula (I) or (II): ##STR20## wherein R 1 is at least one member selected from the group consisting of a hydrogen atom and an alkyl group having 1 to 6 carbon atoms, R 2 is at least one member selected from the group consisting of methyl and phenyl groups, R 3 is at least one member selected from the group consisting of R 4 --, R 5 O-- and R 6 NH-- (wherein R 4 , R 5 and R 6 independently represent an alkyl group having 1 to 22 carbon atoms or an alkenyl, aryl, aralkyl or alkylaryl group having 3 to 22 carbon atoms), R 9 and R 10 independently represent an alkyl group having 1 to 22 carbon atoms or an alkenyl, aryl, aralkyl or alkylaryl group having 3 to 22 carbon atoms, R 3 may be the same as or different from R 9 and R 10 , with the proviso that at least one of R 3 , R 9 and R 10 is a substituent having at least 8 carbon atoms or a polymerizable alkenyl group, and m and n are mean values per molecule which satisfy the requirements of m=0.5 to 2.7, n=0.3 to 2.5 and m+n=0.8 to 3.
