Patent attributes
The invention relates to a novel metal mold having anti-adhesive properties comprising a base metal mold and an anti-adhesive layer comprising a fluorinated alkyl phosphoric acid derivative or a fluorinated alkyl poly-phosphoric acid derivative, including a phosphorous atom and an alkyl chain. The anti-adhesive layer is bonded directly onto a surface of the base metal mold. The base metal mold may be e.g. Nickel, and said fluorinated alkyl phosphoric acid derivative or said fluorinated alkyl poly-phosphoric acid derivative may be selected from the group consisting of phosphonic acids, phosphonic acids, phosphonates and phosphonate salts, phosphonates and phosphonate salts, or their respective oligomers, such that the phosphorous atom is coupled directly to the alkyl chain, such that the phosphorous atom is coupled directly to the alkyl chain.
