Appeal No. 1996-1942 3
Application No. 07/977,834
THE INVENTION
The invention is directed to a microencapsulated adhesive composition, a method
for preparing the composition and a product prepared from the method, comprising an
acrylate or methacrylate monomer incorporated in a microcapsule. Other features of the
claimed subject matter are set forth in the following illustrative claims.
THE CLAIMS
Claims 1, 15, and 21 are illustrative of appellant’s invention and are reproduced
below:
1. A method of producing a microencapsulated adhesive comprising:
providing a mixture containing as a major component an alkyl acrylate
or methacrylate monomer, or a mixture thereof, and a free radical initiator;
microencapsulating said mixture of monomer and initiator;
heating said microencapsulated monomer and initiator for a time and at
a temperature sufficient to cause said monomer to polymerize inside said
microcapsules.
15. A microencapsulated adhesive composition comprising:
an adhesive produced from a monomer or monomers including as a
major component an alkyl acrylate or methacrylate, or a mixture thereof,
encapsulated in microcapsules, wherein said microencapsulated adhesive is initially
non-tacky but exhibits tacky properties upon application of external forces.
