Patent ID: 7649045

Claim:
An aqueous film forming composition that adheres to mammalian skin and related substrates comprising: a aqueous dispersion of blend of two or more polymers comprising a) from 10 to 30% by weight of one or more hard polymers having a Tg of 40 to 75° C. and an average particle size greater than 30 nm; and b) from 70 to 90% by weight of one or more soft polymers having a Tg of 0 to 37° C. and an average particle size of 360 to 800 nm; wherein the polymer blend at 37° C. has a range of dynamic storage modulus of from 5×10 4 and 1×10 8 dynes/cm 2 at a frequency of 10 −1 rad/sec to a corresponding dynamic storage modulus of from 1×10 6 and 1×10 8 dynes/cm 2 at a frequency of 10 2 rad/sec.
