Lascaux acrylic thermoplastic polymer adhesive (498 HV) is a methyl
methacrylate and butyl acrylate thickened with acrylic butylester,
and having a pH 8-9 and is biocide stable
(<URL:http://www.lascaux.ch>).  The adhesive can be initially
thinned in water.  Once it is dried it becomes insoluble in water,
white spirits, naphtha, etc., however it is soluble in acetone,
toluene and xylene.  It appears to be age resistant and non-cross
linking (based on the manufacture).  I suggest taking a look at:
Duffy, M. C. 1989.  A Study of Acrylic Dispersion used in the
Treatment of Paintings. JAIC vol. 28, no. 2, pp.: 67-77.  This seems
like a good study in several types of Lascaux.

It seems that Lascaux series has mostly been use for the lining
painting (introduced in 1972), at least in the past.  See:

    Percival-Prescott, W. and P. Boissonnas. 1974.
    The Lining Cycle. in Conference on Lining Techniques, Greenwich.
    Other applications include mounting paper, wood and plaster.

You might also want to take a look some of the articles listed
below:

    Humanities Research Center In (I believe that they use Jade 403,
    but do cite one of the Lascaux' in the references):
