The water-and-oil repellant composition of the invention including an aqueous dispersion of a pyrazole blocked hydrophobic polyisocyanate containing a pyrazole blocked hydrophobic polyisocyanate represented by the following formula (I) and a non-ionic surface active agent, and a water-and-oil repellant component having a perfluoroalkyl group with 6 carbon atoms or less is provided:
R(—NH—CO—Z)
m
(I)
[in the formula (I), m represents an integer of 2 or more; R represents a residue after an “m” number of isocyanate groups have been removed from a polyisocyanate compound with an “m” number of isocyanate groups; Z represents a residue, which is the same or different from each other, after hydrogen atoms have been removed from active hydrogen-containing compounds that are capable of reacting with an isocyanate group, and at least two of the Z's are a pyrazole groups represented by the formula (II):
in the formula (II), n represents an integer of from 0 to 3; if n is 1 or higher, R
1
, which is the same or different from each other, represents an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an aralkyl group having 7 to 12 carbon atoms, an N-substituted carbamyl group, a phenyl group, —NO
2
, a halogen atom, or —CO—O—R
2
(in the formula, R
2
is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms)}].
