A method of manufacturing a mineral fibre thermal insulation product comprises the sequential steps of: Forming mineral fibres from a molten mineral mixture; Spraying a substantially formaldehyde free binder solution on to the mineral fibres, the binder solution comprising: a reducing sugar, an acid precursor derivable from an inorganic salt and a source of nitrogen; Collecting the mineral fibres to which the binder solution has been applied to form a batt of mineral fibres; and Curing the batt comprising the mineral fibres and the binder which is in contact with the mineral fibres by passing the batt through a curing oven so as to provide a batt of mineral fibres held together by a substantially water insoluble cured binder.

The present disclosure relates to novel multiple trigger negative working photoresist compositions and processes. The processes involve removing acid-labile protecting groups from crosslinking functionalities in a first step and crosslinking the crosslinking functionality with an acid sensitive crosslinker in a second step. The incorporation of a multiple trigger pathway in the resist catalytic chain increases the chemical gradient in areas receiving a low dose of irradiation, effectively acting as a built in dose depend quencher-analog and thus enhancing chemical gradient and thus resolution, resolution blur and exposure latitude. The photoresist compositions and the methods are ideal for fine pattern processing using, for example, ultraviolet radiation, beyond extreme ultraviolet radiation, extreme ultraviolet radiation, X-rays and charged particle rays.
