A polyurethane resin aqueous dispersion comprising:
- dispersion particles incorporating a self-emulsifying polyurenthane resin (A) with an anionic group, and an essentially straight chain polyurethane resin (B-PU) with a flow start temperatue (X) of no more than 60° C., a crystallization temperature (Y) within a range from 0 to 50° C. and a hydrophobic property;
- and an aqueous medium,
- the relative proportions of the polyurethane resin (A) and the polyurethane resin (B-PU) being within a range from (A)/(B)=99/1 to 50/50, and
- the polyurethane resin (B-PU) being obtained by a reaction of 60 to 95% by weight of a straight chain aliphatic polyol (b-5) and 5 to 20% by weight of a diisocyanate (b-6.)
