Abstract: The present invention provides a stencil sheet roll formed by winding up a stencil sheet to form a roll, the sheet including a thermoplastic resin film and a porous support laminated thereto, wherein the compression elastic modulus of the sheet is not less than 32 kg/cm.sup.2. The invention also provides a stencil sheet roll formed by winding up a stencil sheet to form a roll, the sheet including a thermoplastic resin film and a porous support laminated thereto and having been subjected to calender treatment. Also disclosed is a method for manufacturing a stencil sheet roll comprising laminating a thermoplastic resin film to a porous support to form a stencil sheet, subjecting the stencil sheet to calender treatment, and winding up the calender-treated stencil sheet to form a roll.

Abstract: This invention relates to a thermosensitive recording material containing at least one of durene derivative represented by the formula (I): ##STR1## wherein Z represents CH.sub.2 OX or H, X represents an alkyl group, a cycloalkyl group, a substituted or unsubstituted aralkyl group or aryl group, or --COR group where R represents an alkyl group or a substituted or unsubstituted aryl group,in a recording layer which contains a leuco dye and a color-developing agent which reacts with said dye so as to form a color by heating, and the thermosensitive recording material having high color sensitivity can be obtained.
