摘要:
A washable dry erase coloring composition comprising an acid dye or polymeric dye colorant, a dye vehicle, a release agent, and a dyeblocker additive. The dyeblocker additive is either a sulfonated naphthalene condensation product or a sulfonated phenol-formaldehyde condensation product. The dry erase coloring composition is suitable for use in marking on a whiteboard and enhances fugitivity from skin and fabrics. The dry erase coloring composition may optionally contain a film forming resin. More specifically, the invention is, in one preferred embodiment, a washable erasable whiteboard marker ink comprising an acid dye or polymeric dye, water, a film forming resin, a release agent and a sulfonated phenol-formaldehyde condensation product. In addition, the invention also includes a method of transferring an image from a whiteboard or non-porous surface to paper. This method comprises the steps of: (a) drawing an image on a whiteboard or non-porous surface with a washable coloring composition containing a dyeblocker; (b) applying a moistened paper to the image; (c) rubbing the moistened paper to transfer the image from the whiteboard to the paper; and (d) removing the paper.
摘要:
Animal tissue and the like having silver sulfadiazine incorporated therein is useful as a covering for burns and/or wounds. The silver sulfadiazine is incorporated in the tissue by soaking the tissue in an ammoniacal silver sulfadiazine solution or suspension. When the silver sulfadiazine is so incorporated in the tissue via an ammonium solution, more silver is found to be present than would normally be expected and the effectiveness of the thus treated tissue as a wound covering increases.

A sportswear cooling system for enhancing physical activity for a wearer is provided which has a first compartment containing a cooling solution and a second compartment containing water. The first compartment is positioned within the second compartment and the walls of the first compartment are adapted to be ruptured so that when the cooling solution and water combine an endothermic reaction is produced calculated to cool a portion of the body upon application.

Methods and systems are provided for pricing products based on qualifiers. A pricelist for a product being offered is defined. Defining the pricelist includes establishing one or more qualifiers for determining a price of the product and where each qualifier established for the pricelist is an attribute of the pricelist that results in a price variation for the product being offered. The qualifiers necessary to fully qualify a price of the product are encoded into a pricelist identifier referencing the price list. The pricelist is a price of the product once the qualifiers necessary to fully qualify a price have been established. The prices of the product may be differentiated and retrieved based on an unlimited number of qualifiers.
