Aqueous coating composition

An aqueous coating composition comprising (A) an amino group-containing organopolysiloxane, (B) water and (C) at least one of

• (i) a surface-active agent represented by the following general formula (I):
• wherein R1 to R4 are each independently an alkyl group having 1 to 8 carbon atoms, R5 and R6 are each independently an alkylene group having 1 to 6 carbon atoms, R7 and R8 are each independently a member selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms and an acyl group having 2 to 6 carbon atoms, and m and n are each an integer of 0 to 40, provided that in and n are not 0 at the same time and that the value of m+n is a number of 1 to 40 on the average;
• and
• (ii) a nonionic surface-active agent containing a perfluoroalkyl group and an alkylene oxide group;
• the component (C) being present in a content of from 0.01% by weight to 5% by weight based on the total weight of the components (A), (B) and (C), and an alcohol being present in the composition in an amount not more than 10% by weight of the total weight of the composition
• wherein
• (A) is a hydrolysis-condensation product of an amino group-containing alkoxysilane represented by the following general formula (II):
• R9R10pSi(OR11)3-p (II)
• wherein R9 is an amino group-substituted alkyl group, R10 is an alkyl group having 1 to 8 carbon atoms, R11 is an alkyl group having 1 to 6 carbon atoms, and p is an integer of 0 to 2;
• or
• (A) is a co-hydrolysis-condensation product of an amino group-containing alkoxysilane represented by the following general formula (II):
• R9R10pSi(OR11)3-p (II)
• wherein R9, R10 and R11 are as defined above;
• and an alkoxysilane represented by the following general formula (III):
• R124-aSi(OR13)a (III)
• wherein R12 is a group selected from an alkyl group having 1 to 6 carbon atoms, a substituted alkyl group, an aryl group and a vinyl group and R13 is an alkyl group having 1 to 6 carbon atoms;
