Patent ID: 7850821

Claim:
A household thin paper comprising a polyester-based compound represented by General Formula (1): wherein: R 1 is HO— or HO(R 2 O)a-, R 2 is an alkylene group having 2 or 3 carbon atoms, only one type of R 2 O or two types of R 2 O are attached at random or as a block to the compound, “a” is 1 to 200, all “a”s are same or different in a molecule, b is 2 to 100, and R 3 is a hydrogen atom or a group represented by General Formula (2); said polyester-based compound is added to pulp raw material in an amount of 0.05 to 6.0% by mass based on said pulp raw material; the household thin paper further comprises a moisture retention agent; said polyester-based compound represented by General Formula (1) and said moisture retention agent are contained in an amount of 5 to 60% by mass based on a weight of a sheet in which they are contained; a basis weight per 1 ply is 10 to 40 g/m 2 ; and said polyester based compound has a mass average molecular weight of 1,000 to 200,000, is a softening agent and is water soluble.
