PROBLEM TO BE SOLVED: To provide pressure-bonded recording paper subjected to ink-jet printing on an adhesive layer surface, free from stain of the peeled information print surface when peeled after bonding, good in adhesion and peelability and also free from decline in pseudoadhesive strength with time, etc. SOLUTION: The press-bonded recording paper is such that an adhesive layer is blended with an adhesive and a microparticle filler. In the pressure-bonded printed paper, the microparticle filler uses regenerated particles derived from waste paper treatment, particularly such regenerated particles as to contain calcium, silicon and aluminum in a mass ratio of (30-82):(9-35):(9-35) in terms of oxide basis, which are obtained by subjecting at least deinked floss as the main feedstock to a dewatering step, drying step, baking step and grinding step.
