Title:
SOFTENER FILLED IN PHOTO SPECTRAL SEPARATING CASE
Document Type and Number:
Japanese Patent JP3308486
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method capable of retaining a stabilized quality for a long period suppressing change in color caused by sun light by including a liquid softener finishing agent composition in a photo spectral separating case having a photoabsorption parameter in a specific range.
SOLUTION: This method uses a container having photoabsorption parameters AB calculated from the formula, AB=λb/λc[λb and λc are each visible light of 400 nm<λb, λc<800 nm and λb satisfies dTb/dλ=0 and (d2Tb/dλ2)<0, λc satisfies dTc/dλ=0 and (d2Tc/dλ2<0,; Tb is a transmission function of the section of the container at the arbitrarily wavelength in 400 to 800 nm, Tc is the transmission function of the prescribed arbitrarily wave length of the liquid softener finishing agent composition setting the maximum photo transmission in 400 to 800 nm range as 1], as 0.90≤AB≤1.10. The softening agent article is obtained by charging the liquid softening agent composition including a tertiary amine (salt) containing alkyl groups having ester linkage or their quaternary compounds and a water soluble dye into the container manifesting the prescribed photoabsorption parameter.
