Composition for non-aqueous secondary battery adhesive layer, adhesive layer for non-aqueous secondary battery and method for producing the same, laminate for non-aqueous secondary battery and method for producing the same, and non-aqueous secondary battery

A composition for a non-aqueous secondary battery adhesive layer, comprising a particulate polymer,

• wherein a value of pressure sensitivity of adhesion strength as obtained using the following formula (1) is greater than 20 and less than 80:
• pressure sensitivity of adhesion strength(N/(m·MPa))=(T3−T1)/2 (1)
• where T1 represents an adhesion strength (N/m) between a polyethylene separator and an adhesive layer for a non-aqueous secondary battery adhesive layer that is obtained from the composition for a non-aqueous secondary battery adhesive layer when the polyethylene separator and the adhesive layer are bonded by pressing at 25° C. and a pressure of 1 MPa for 10 seconds, and T3 represents an adhesion strength (N/m) between the polyethylene separator and the adhesive layer when the polyethylene separator and the adhesive layer are bonded by pressing at 25° C. and a pressure of 3 MPa for 10 seconds;
• wherein the particulate polymer has a core-shell structure comprising a core and a shell partially covering an outer surface of the core,
• the core has a glass transition temperature of −50° C. or higher and 25° C. or lower,
• the shell has a glass transition temperature of 50° C. or higher and 200° C. or lower, and
• a mass percentage of the shell with respect to a total of the core and the shell is 2% by mass or more and 15% by mass or less.
