Aspects of the present disclosure generally describe polyarylether ketones and methods of use. In some aspects, a composition includes one or more polymers of formula (IV): ##STR00001##

A wafer laminate has an adhesive layer (3) sandwiched between a transparent substrate (1) and a water (2), with a circuit-forming surface of the wafer facing the adhesive layer. The adhesive layer (3) includes a first cured resin layer (3a) disposed adjacent the substrate and having light-shielding properties and a second cured resin layer (3b) disposed adjacent the wafer and comprising a cured product of a thermosetting resin composition.
