Abstract: Provided is a PSA sheet having excellent moisture resistance with reduced gas emission. The sheet body provided by this invention is a laminate sheet body having a PSA layer on at least one face. The sheet body has a moisture permeability of less than 90 ?g/cm2 per 24 hour measurement period in in-plane direction of bonding interface of PSA layer, with the sheet body having an internal volume (bulk) forming a permeation channel that has a prescribed length of 2.5 mm, the moisture permeability determined based on a modified MOCON method, at a permeation cell temperature of 40° C., with humidistat gas at a temperature of 40° C. and 90% relative humidity supplied to a wet chamber. It also has an amount of thermally released gas of 10 ?g/cm2 or less, determined at 130° C., over 30 minutes, by gas chromatography/mass spectrometry.

Abstract: Provided is a PSA composition capable of achieving excellent moisture resistance. The PSA composition provided by the present invention comprises a polymer A and a polymer B different from the polymer A. In each of the polymer A and the polymer B, isobutylene is polymerized at a ratio of 50% by weight or higher.

Abstract: Provided is a PSA sheet that achieves both bonding reliability at a high temperature and reduction of outgassing. The PSA sheet provided by this invention comprises a substrate layer and a PSA layer provided to one face of the substrate layer. The PSA sheet exhibits a 180° peel strength of 1 N/20 mm or greater to stainless steel at 60° C. It has an amount of thermally released gas of 10 ?g/cm2 or less, determined at 130° C. for 30 minutes by GC-MS.

Abstract: The present invention provides a pressure-sensitive adhesive (PSA) sheet that achieves both low initial adhesiveness and strong adhesiveness upon use and has excellent transparency of the PSA layer. The PSA sheet provided herein includes a PSA layer having a haze value of 1.0% or less. The PSA sheet is configured so that a pressure-sensitive adhesive strength N1, after the PSA layer is attached to a stainless steel plate and left at 23° C. for 30 minutes, is 1.5 N/20 mm or less, and a pressure-sensitive adhesive strength N2, after the PSA layer is attached to a stainless steel plate and heated at 80° C. for 5 minutes, is 10.0 N/20 mm or more.

Abstract: The present invention provides a pressure-sensitive adhesive (PSA) sheet that achieves, in the form having a support substrate, both low initial adhesiveness and strong adhesiveness during use. The PSA sheet provided in this application includes a support substrate and a PSA layer laminated on at least one side of the support substrate. The PSA layer has a thickness of 3 ?m or more but less than 100 ?m. The support substrate has a thickness of 30 ?m or more. The PSA sheet is configured so that a relationship between an elastic modulus Et? [MPa] of the PSA sheet and a thickness Ts [mm] of the support substrate fulfils the following formula: 0.1 [N·mm]<Et?×(Ts)3. The adhesive strength N2 after the PSA layer is attached to a stainless steel plate (SUS304BA plate) and heated at 80° C. for 5 minutes is 20 times or more of an adhesive strength N1 after the PSA layer is attached to a stainless steel plate (SUS304BA plate) and left at 23° C. for 30 minutes.

Abstract: An estimated shortfall by article and time period is first computed. Then, based on the estimated shortfall, etc., an expected profit of each of the first through m-th ordered pieces of each article is computed, and sorted in order from the highest expected profit. Based on the sorting result, for example, an order pattern with which the highest profit can be expected in the order budget is presented. The above mentioned process can be separately performed between weekdays and holidays if the sales characteristics are different between them.
