This invention relates to a paper substrate containing high surface sizing and low internal sizing and having high dimensional stability, as well as methods of making and using the composition.

Paper substrates containing high surface sizing and low internal sizing and having high dimensional stability

Expandable microspheres formed by suspension polymerization using a shot growth method are provided. The microspheres are formed of a continuous, gas impermeable shell surrounding a blowing agent. The shell includes a first polymer layer formed from primary monomers and a second layer that includes a chemically reactive monomer or a high Tg monomer. To form the microspheres, the primary monomers are polymerized in a reaction vessel to an approximate 90% polymerization, at which time a secondary monomer that is either a monomer having a Tg of at least 85&#xb0; C. or a chemically reactive monomer, is added to the reaction vessel to drive the polymerization reaction to completion. The outer layer thus contains either a larger amount of the high Tg monomer or a chemically reactive monomer that possesses the ability to covalently bond a cationic species. The microspheres may be used in papermaking processes to increase the paper bulk.

The invention involves papers having either an internal starch or a size press applied starch and a boron-containing compound which is added in proportion to the starch and which is believed to interact with the starch to provide improved physical and mechanical properties in the paper. Method of forming the papers are also disclosed.

The present invention relates to paper substrates containing either an internal starch or a size press applied starch and a boron-containing compound and having improved physical and mechanical properties, as well as methods of making and using the same.

A heat transfer recording sheet comprising a support layer; an adhesive layer; and at least one ink receiving layer comprising a microporous polymeric film including at least one thermoplastic polymer. The thermoplastic polymer may be blended with a hydrophilic melt additive prior to extrusion and stretching or an already extruded and stretched microporous polymeric film may be coated with an additional layer of inorganic pigment and binder. The recording sheet containing a printed image is transferred onto target substrates such as paper and textiles.
