Abstract
The present disclosure is directed towards a paper product which can remain intact prior to and during usage and can self-disintegrate over time. Such a paper product can occupy less space in a user's waste bin following usage when compared with a similar paper product that does not self-disintegrate. Such a paper product can be treated with a topical binder that includes a sublimable material. The sublimable material can sublime away from the paper product over time thereby reducing the ability of the fibers of the paper product to remain bonded together.
