Claim 0:
1. An electrolytic capacitor comprising:
an anode comprising a dielectric layer on said anode;
a first mordant layer on said dielectric wherein said first mordant layer comprises a mordant compound of Formula A:, wherein:
R1 and R2 is independently selected from H; cation, linear alkyl, cyclic alkyl or substituted alkyl of 1 to 10 carbons;
R3 is selected from —CR4R5R6 wherein R4 represents a hydrogen, an alkyl of 1-20 carbons or an aryl of 6-20 carbons; R4 and R5 can be taken together to represent a cyclic alkyl or substituted cyclic alkyl or (—CR6OP(O)OR1OR2)n;
R5 represents an alkyl of 1-20 carbons or an aryl of 6-20 carbons; R4 and R5 can be taken together to represent a cyclic alkyl or substituted cyclic alkyl or (—CR6OP(O)OR1OR2)n;
R6 represents a hydrogen, an alkyl of 1-20 carbons or an aryl of 6-20 carbons; and
n is an integer from 1 to 20; and
a crosslinker; and
a primary conductive polymer layer on said first mordant layer.
