Patent ID: 7749319

Claim:
A composition for surface conditioning comprising bivalent or trivalent metal phosphate particles and having a pH of 3 to 12, wherein a D 50 of the bivalent or trivalent metal phosphate particles is 3 μm or less, and the composition for surface conditioning comprises an amine compound having a molecular weight of 1000 or less, and at least one metal alkoxide in a content of from 0.01 to 1000 parts by weight per 100 parts by weight of the solid content of the metal phosphate particles and having the following formula: R 1 -M-(R 2 ) n (OR 2 ) 3-n wherein M represents silicon, titanium or aluminum; R 1 represents an alkyl group having 1 to 6 carbon atoms and being unsubstituted or substituted with an organic group, an epoxyalkyl group having 1 to 11 carbon atoms, an aryl group, an alkenyl group having 1 to 11 carbon atoms, an aminoalkyl group having 1 to 5 carbon atoms, a mercaptoalkyl group having 1to 5 carbon atoms, or a halogenoalkyl group having 1 to 5 carbon atoms; R 2 represents an alkyl group having 1 to 6 carbon atoms; and n is 0, 1, or 2.
