Abstract
Composite materials such as composite particles have a solid non-elastomeric continuous phase made of an organic polymer having a glass transition temperature of at least 25° C. Dispersed within this solid non-elastomeric continuous phase are many multi-compartment porous chemically crosslinked elastomeric particles that have a mode particle size of at least 1 μm and up to and including 10 μm. The composite particles can be used as toner particles in electrophotographic imaging methods to provide fused toner images and especially stacked fused toner images.
Claims14
A composite material comprising a solid non-elastomeric continuous phase comprising an organic polymer having a glass transition temperature of at least 40° C. and up to and including 120° C. as measured using differential scanning calorimetry at a scanning rate of 20° C./minute, and having dispersed within the solid non-elastomeric continuous phase, a plurality of multi-compartment porous chemically crosslinked elastomeric particles that have a mode particle size of at least 1 μm and up to and including 10 μm,
- wherein the organic polymer comprises a polyester, styrene-acrylic copolymer, cellulosic polymer, polyamide, polyimide, vinyl ester polymer, mono-olefin polymer, vinyl ether polymer, vinyl ketone polymer, or a polymer formed from one or more α-methylene aliphatic mono-carboxylic acid esters.
