摘要:
A hard coat composition comprising a cationic acrylic polymer is disclosed. The hard coat is suitable for application to a substrate, and can be used without an adhesive promoting primer.
摘要:
Disclosed are replenisher compositions and methods of replenishing pretreatment compositions. The methods include adding a replenisher composition to a pretreatment composition wherein the replenisher composition includes: (a) a dissolved complex metal fluoride ion wherein the metal ion comprises a Group IIIA metal, Group IVA metal, Group IVB metal, or combinations thereof; (b) a component comprising an oxide, hydroxide, or carbonate of Group IIIA, Group IVA, Group IVB metals, or combinations thereof; and optionally (c) a dissolved metal ion comprising a Group IB metal, Group IIB metal, Group VIIB metal, Group VIII metal, Lanthanide Series metal, or combinations thereof.
摘要:
The invention includes a composite material for use in a security device including a radiation diffracting component that exhibits a first optical effect and a photochromic component that exhibits a second optical effect. The composite material is particularly suited for use in authenticating articles, such as currency.
摘要:
The invention includes a radiation diffracting member having a crystalline structure comprising an ordered periodic array of hollow particles. The radiation diffracting member also includes a matrix material in which the array of particles is received.
摘要:
Disclosed are methods for treating metal substrates that include contacting the substrate with a pretreatment composition comprising a rare earth metal and a zirconyl compound. The present invention also relates to coated substrates produced thereby and further to substrates additionally coated with an electrophoretically applied coating composition.
摘要:
Disclosed are methods for making polymeric substrates, such as polycarbonate substrates, at least partially coated with a haze-free, self-healing coating. Also disclosed are substrates made by such methods.
摘要:
A radiation curable coating comprising the reaction product of a polyol and a polycarboxylic acid/anhydride is disclosed. The reaction product may be made from at least some biomass derived compound. Coatings wherein this reaction product is further reacted with a hydroxyl-carboxylic acid and/or a compound having a radiation curable moiety are also disclosed, as are substrates coated with any of these coatings.
