Abstract: An object of the present invention is to provide a radiation curable pressure-sensitive adhesive sheet with excellent storage stability, which can suppress the progress of curing during storage and maintain excellent level difference absorbability and stress relaxation properties for a long time. A radiation curable pressure-sensitive adhesive sheet 1 of the present invention has a pressure-sensitive adhesive layer 10 that is cured by irradiation with radiation. The pressure-sensitive adhesive layer 10 contains a photopolymerization initiator 11a and a crosslinking agent 11b, and the curing by irradiation with radiation is curing by a reaction between the photopolymerization initiator 11a and the crosslinking agent 11b. In the radiation curable pressure-sensitive adhesive sheet 1 of the present invention, when the pressure-sensitive adhesive layer 10 is stored at 50° C. for 4 weeks, a rate of change in residual stress (N/cm2) expressed by the following equation is 70% or less.


Residual stress change rate (%)=(residual stress after storage at 50° C. for 4 weeks−initial residual stress)/(initial residual stress)×100

Abstract: A fire resistant (FR) pressure sensitive adhesive (PSA) comprises a blend of: a) a (meth)acrylate polymer comprising cationic monomer units; and b) a non-halogenated flame retardant. In some embodiments, the cationic monomer units comprise cationic quaternary amine groups. The (meth)acrylate polymer may additionally comprise anionic monomer units, in which case the molar ratio of anionic monomer units present in the polymer to cationic monomer units present in the polymer is typically less than 0.9. The FR PSA may be aqueous based and may be free of common solvents. The FR PSA may demonstrate improved flame retardance with good compatibility between PSA and flame retardant, and may retain compatibility even at high loadings of flame retardant.
