An electrophotographic composition comprising composite particles comprising particles of wax dispersed in a matrix comprising an olefin polymer having acid and/or ester side groups, wherein the wax has a melting point of at least 130 degrees C.
A method of producing an electrophotographic composition, said process comprising
- mixing wax with a molten resin comprising an olefin polymer having acid and/or ester side groups,
- allowing the mixture to cool to form a matrix comprising an olefin polymer having acid and/or ester side groups surrounding dispersed particles of solid wax, grinding the resulting mixture to form composite particles, and
- dispersing the composite particles in a liquid carrier, wherein the wax has a melting point that is higher than the melting point of the olefin polymer in the matrix.
Use of a wax having a melting point of at least 130 degrees C. to improve the adhesion of a varnished electrophotographically printed image onto a print medium.
