Abstract: The invention describes a composition and method of providing an improved recording material, such as an ink receptive recording material or thermally responsive record material useful for linerless labels. The record material comprises a support having provided thereon on one surface an adhesive material, and on at least one other surface, an ink receptive coating or a heat sensitive imaging coating. The method comprises applying to a first surface a first layer of a coating of an ink receptive material or of a heat sensitive color-forming composition comprising a binder material and a substantially colorless dye precursor and an acidic developer material in substantially contiguous relationship. The adhesive is heat activated.

Abstract: The invention teaches a method of efficiently dewatering a microcapsule slurry to form a water re-suspendable filter cake of microcapsules. The process comprises providing an aqueous slurry of microcapsules dispersed in an aqueous solution; adding an agglomeration agent and dispersing the agglomeration agent into the aqueous slurry; adjusting the pH to a pH level sufficient to agglomerate the dispersed microcapsules; and filtering the aqueous slurry of microcapsules by gravity, vacuum or pressure filtration to thereby form a filter cake of dewatered microcapsules. The agglomeration agent is sodium polyphosphate, sodium tetrapolyphosphate, sodium hexametaphosphate, and/or sodium tripolyphosphate; or with anionic microcapsules or coatings even alkaline earth metal salts such as magnesium chloride, calcium chloride or barium chloride, or even aluminum salt such as aluminum chloride.

Abstract: A method, and apparatus, for determining bend resistance of a sample includes applying a weight to a sample and measuring an amount of deflection of the sample caused by applying the weight. The sample is provided on a sample holder and an initial position of the sample is measured with respect to the sample holder. A weight is applied to the sample and a change in position from the initial position to a deflection position of the sample due to the weight applied to the sample is measured. An amount of deflection of the sample is determined by dividing the change in position by the basis weight.
