PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE TAPE

The present invention provides a pressure-sensitive adhesive composition, including: an acrylic copolymer and a crosslinking agent. The acrylic copolymer is a reaction product of a mixture of the following monomers: a first alkyl (meth)acrylate, an alkyl group in the first alkyl (meth)acrylate having at least 6 carbon atoms; a second alkyl (meth)acrylate, an alkyl group in the second alkyl (meth)acrylate having 1 to 5 carbon atoms; and a vinyl carboxylic acid, the weight ratio of the vinyl carboxylic acid to the mixture being 4% to 5%. The crosslinking agent is an organometallic chelating agent. The weight ratio of the organometallic chelating agent to the mixture is 0.05% to 0.25%. The pressure-sensitive adhesive composition does not contain an effective amount of a tackifier. The present invention further provides a pressure-sensitive adhesive solution, a pressure-sensitive adhesive tape, and a method for preparing the same. The pressure-sensitive adhesive of the present invention is a removable pressure-sensitive adhesive, and is applicable in hot weather and cold weather, and the adhesiveness of the pressure-sensitive adhesive does not decrease over time.

Adhesive bonding composition and electronic components prepared from the same

A curable resin or adhesive composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and at least one energy converting material, preferably a phosphor, capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.
