Tissue products are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition may be incorporated into the tissue web by being combined with the fibers that are used to form the web. Alternatively, the additive composition may be topically applied to the web after the web has been formed. After the additive composition is applied to the web or otherwise incorporated into the tissue web, the tissue web is embossed. During embossing, the additive composition forms well defined embossments in the web that are water resistant. In one embodiment, the additive composition may also be used to bond multiple tissue webs together to form a multiple ply product during the embossing operation.

A process for producing a photothermographic recording material having a support and a photo-addressable thermally developable element containing photosensitive silver halide in catalytic association with a substantially light-insensitive silver salt of an organic carboxylic acid, an organic reducing agent for the substantially light-insensitive silver salt of an organic carboxylic acid in thermal working relationship therewith and a binder including a water-soluble binder, a water-dispersible binder or a mixture of a water-soluble binder and a water-dispersible binder, comprising the steps of: (i) producing an aqueous dispersion or aqueous dispersions containing photosensitive silver halide, a substantially light-insensitive silver salt of an organic carboxylic acid, an organic reducing agent for the substantially light-insensitive silver salt of an organic carboxylic acid and a binder including a water-soluble binder, a water-dispersible binder or a mixture of a water-soluble binder and a water-dispersible binder; (ii) coating the aqueous dispersion or aqueous dispersions onto a support thereby forming a photo-addressable thermally developable element on the support, wherein at least 80 mol % of the photosensitive silver halide is silver iodide and the aqueous dispersion further contains or the aqueous dispersions further contain a diazine compound.

Hydrophilic dispersions of stable nano-sized particles are provided comprising: (a) a water-insoluble or water-soluble active compound, wherein said active compound is selected from the group consisting of a macrolide antibiotic, donepezil hydrochloride, an azole compound and a taxane; and (b) an amphiphilic polymer which wraps said active compound in a non-crystalline manner to form a nano-sized molecular entity in which no valent bonds are formed.

The present invention relates to a process for preparing a microencapsulated pigment, which comprises adding a polymerizable surfactant having a hydrophilic group, a hydrophobic group and a polymerizable group, a polymerization initiator and an aqueous medium to a wet pigment, and conducting emulsion polymerization to encapsulate pigment particles with a polymer. Also disclosed are a microencapsulated pigment obtained by using this preparation process and an ink for ink jet recording containing at least the microencapsulated pigment and water.
