This message is an appendix to my previous message researching Poly
Vinyl Alcohol (PVA) as part of a laser transfer paper.  I was wondering
whether "Dissolvo" paper was made with PVA.  It seems not.  A 1969 US
patent:

  http://www.freepatentsonline.com/3431166.pdf

indicates it is not.  However, perhaps "dissolvo" paper could be made by
other means, perhaps with fibres of partially hydrolyzed PVA.  (See my
previous message for how North Koreans wear PVA fabric clothes.) The
term "dissolvo" seems to be used in a generic fashion, in addition to
being a trademark.  It is is also used to describe water-soluble plastic
films, some of which are made with PVA.

Daymark Technologies http://www.dissolvo.com AKA
http://www.daymarktechnologies.com make water soluble paper, largely for
use by welders.  They are a subsidiary of Gilbreth, whose "dissolvo"
paper is mentioned in some patents.  This does not seem to use PVA:

"Sodium Caboxy Methyl Cellulose and wood pulp".

Dissolvable paper is used for magic tricks and according to Daymark
Technologies, for sewing patterns which can be sewn together with the
fabric, and then washed away.

Has anyone use this for laser toner transfer?  I haven't fully
researched where it can be purchased.

I've tried it and it worked pretty well. See message #27445. I also posted a couple of photos in the Photo section in a folder called "Dissolvo Paper Experiment". Only the true Dissolvo brand worked well, other, cheaper water soluble papers left some residue.
