A transaction card processing and activation system comprising the identification of a unique identifier corresponding to an aggregate of transaction cards of affiliated or non-affiliated card issuers and the activation of each transaction card corresponding to the unique identifier of the aggregate irrespective of the number, types, or card issuers of the transaction cards. Additionally, the present invention allows a point of sale entity to initiate the activation of each of the multiple, disparate transaction cards in the aggregate by merely processing the unique identifier associated with the aggregate.

Specific hydroxysilanes of formula (I), a method for the production thereof, the use thereof as a constituent of moisture-curing compositions, and silane-functional compounds produced therefrom, in particular silane-functional polymers and isocyanatosilanes. The hydrosilanes can be produced in a simple process with a high degree of purity and are storage-stable after production. Production from the reaction of lactides with aminosilanes is particularly advantageous. Hydroxysilane of formula (I), where n is 1 or 2.

A biodegradable pressure-sensitive adhesive which can be readily coated indirectly onto biodegradable carriers, which comprises

at least 60 wt % of at least one polyurethane, and
at least one sulfonated carboxylic ester; and a method for producing a biodegradable adhesive tape, which comprises providing a pressure-sensitive adhesive of the invention as a dispersion in at least one organic solvent; coating this dispersion onto a release liner; removing the organic solvent; and transferring the pressure-sensitive adhesive onto a biodegradable carrier.

This invention relates to a coating comprising prepolymer and monomers for application onto polyurethane for chemical resistance, abrasion resistance, water proof etc. Usually polyurethane is porous and does not have sufficient stain, abrasion and chemical resistance. The said coatings developed using technology of chemical grafting that involves the use of prepolymers, monomers, catalyst, graft initiator, wetting agents, fillers and other ingredients of the composition. The coating thus obtained when applied on the polyurethane allows obtaining graft polymerization, thereby forming a polymeric film chemically attached to the substrate. The polyurethane substrate is reacted with graft initiator which creates the reaction sites on the substrate via free radical mechanism. This in turn renders the substrate receptive to attachment of monomers/prepolymers forming polymeric film that is chemically bonded to the substrate which has then the desired property in terms of stain resistance, abrasion wear, crock, water, chemical resistance and other properties.

The present invention relates to a curing agent for moisture-curing compositions which includes at least one aqueous emulsion of at least one epoxy resin. Curing agents according to the invention are especially used for the accelerated curing of moisture-curing compositions which are based on polyurethane polymers that have isocyanate groups or of silane-functional polymers.
