A method of preparing a resin-fortified polymer emulsion is disclosed. In one embodiment, the method comprises polymerizing at least one monomer in the presence of a surfactant, an initiator, a resin and sugar-based vinyl monomer under emulsion polymerization reaction conditions effective for initiating polymerization, wherein an emulsion polymerization product is formed that comprises a sugar-based vinyl monomer. A composition comprising resin-fortified emulsion polymer comprising a sugar-based vinyl monomer, a resin and at least one emulsion polymerizable monomer is also disclosed. An ink comprising a pigment and a resin-fortified polymer emulsion comprising a sugar-based vinyl monomer, a resin and at least one emulsion polymerizable monomer is also disclosed.

A process for making ink which begins with a leach liquor of Al.sub.2 (SO.sub.4).sub.3 +K.sub.2 SO.sub.4 +Fe.sub.2 SO.sub.4 and other sulfates that are introduced to a surface-cooled crystallizer that drops the Al.sub.2 (SO.sub.4).sub.3 +18H.sub.2 O which is removed from the leach liquor. The leach liquor is then supplied with a mixture which includes K.sub.2 SO.sub.4 into a simple crystallization and evaporation unit to drop Al.sub.2 (SO.sub.4).sub.3 +K.sub.2 SO.sub.4 +24H.sub.2 O. A pressure of 250 PSI and a temperature of 200.degree. C. are then applied in a discrete continuous process that yield a basic sodium or sodium/potassium aluminum sulfate and excess sodium sulfate or sodium/potassium. The excess sodium sulfate or sodium/potassium sulfate is returned to the simple crystallization and evaporation unit. The basic potassium aluminum sulfate (BKAS) and/or basic sodium aluminum sulfate (BNaAS) Na.sub.2 SO.sub.4, 3Al.sub.2 O.sub.3, 4SO.sub.3, 9H.sub.2 O is used as a filler in the making of ink.

An improved method of molding articles from air-laid webs wherein resin is deposited in a dry process onto cellulose fibers prior to air-laying. Cellulose material and a resin-containing airstream are simultaneously fed into a comminuting means such as a hammer mill. The cellulose particles thereby produced have a coating which adheres to the surface of the cellulose particles. The cellulose particles retain substantially all of the dry resin coating when pneumatically conveyed and air-laid into a web. The fiber web produced with the resin-coated particles is suitable for use in a conventional molding process whereby the web is molded under sufficient heat and pressure into a molded article having a uniform resin distribution resulting in improved strength and improved structural integrity.
