Abstract
Abstract A method is described for producing structured wallpapers in which a PVC-free and plasticizer-free structure paste on The basis or inorganic and/or organic fillers and a polymer dispersion of a vinyl acetate copolymer is used. Non-crystallizing sorbite syrup or ethylene glycol as processing retarding agents, paraffin dispersion as hydrophobing agent and micropearls and/or hollow microbeads for increasing the specific volume may also be added to the structure composition.

Other polvmer dispersions have been follnd suitable for example on the basis of vinvl acetate maleic acid di-n-butyl ester and vinyl acetate-acrylic acid ester.

This gives a better strength of the structure composition.
In addition, the starch binds a considerable proportion of the water and liberates the latter slowly during drying.
This prevents rapid evaporation, which could lead to formation of bubhles.

It has further been Eoulld extrernely ac]vantacJeol~s to add to the systerll a certairl amount of an organic processing retarder. It has been found that the addition of 1 - 8 %
by weig}lt rJon-crystallizing sorbite syrup, with respect tc>
the total paste is ver~ advantageous for the working thereof because in addition to the working retardation the viscosity of the structure paste is also positively influenced.
The non-crystallizirlc~ sorbi.te syrup may possibl~ be replaced by ethylene glvcc)l or other organic solvents with correspondin~ properties. Thus it has been found that the ad(3ition of l - 5 ~6 by weight ethylene glycol with respect to the total paste i.s also advantageolls for the working therec)f in certain ca.se-;.
It may also be advantageous to add hyclrophobiny agents to the struct~re paste to impart to the structured wallpaper to be made a water-repellent character to a certain exten-t.
It has been fourld that this can also be achieved hy ad~lition of 1 - 3 % by weiyht para~Efin dispersion with respect tc the total paste.
To reduce the speci.~:ie weight oE the dried structure paste and to -irltensify the structure forlllation tllereoE during drying as w~ll, appropriate adclitives may be added to the ~tructure p~te in relatively srnall amounts hy weig}lt.
To enable the specific volume of the structure paste to be inc-rea~ed during the processing in particular during -the dryiny it has been found advanta~eous to add to the total paste abou-t I - 8 ''6 hy wei~ht c~f so-called rllicropearls.
~lier(lpearls are m1(crocapsll1es WiliCh are filled with a blowirlg agellt and have a diameter of about 10 - 20 um, 2 ~ 3 ~
~onsisting of therrnoplastic plast:ic, and at 120 - 140C
they expand to several times their volume. These micrc-pearls have for example polyrller shells on the basis of meth~lmethacr~late or also an acrylonitrile copolyrrler.
Prefera~)ly, forllls are used which have arl expan6ion ratio of abollt 20. In the structllre paste accorc3ing to the irlventioll thec:e micropearls partially perfortn the function of the ~-lowillg ac~el~t ill the collventi(,)nal PVC plastisols.

These are ex~anded hc)llc~w polymef headq, in the surface of which inor~allic fillers are advanta~ec)uqly embedded. The diameter of such hc~llow microbeads is preferably in the range of 10 - ~0 ~m and their specific volume is about 0.15 g/cm~. Due to the polylller material of the microbead walls and the inorganic filler particles attached thereto, the hollow Illicrc~beads are practically a mixed or,cJanic-irlc)r~allic filler of very high specific vol~lme.

The non-crystallizirlc~ sorbi.te syrup may possibl~ be replaced by ethylene glvcc)l or other organic solvents with correspondin~ properties. Thus it has been found that the ad(3ition of l - 5 ~6 by weight ethylene glycol with respect to the total paste i.s also advantageolls for the working therec)f in certain ca.se-;.
It may also be advantageous to add hyclrophobiny agents to the struct~re paste to impart to the structured wallpaper to be made a water-repellent character to a certain exten-t.
It has been fourld that this can also be achieved hy ad~lition of 1 - 3 % by weiyht para~Efin dispersion with respect tc the total paste.
To reduce the speci.~:ie weight oE the dried structure paste and to -irltensify the structure forlllation tllereoE during drying as w~ll, appropriate adclitives may be added to the ~tructure p~te in relatively srnall amounts hy weig}lt.
To enable the specific volume of the structure paste to be inc-rea~ed during the processing in particular during -the dryiny it has been found advanta~eous to add to the total paste abou-t I - 8 ''6 hy wei~ht c~f so-called rllicropearls.
~lier(lpearls are m1(crocapsll1es WiliCh are filled with a blowirlg agellt and have a diameter of about 10 - 20 um, 2 ~ 3 ~
~onsisting of therrnoplastic plast:ic, and at 120 - 140C
they expand to several times their volume. These micrc-pearls have for example polyrller shells on the basis of meth~lmethacr~late or also an acrylonitrile copolyrrler.
Prefera~)ly, forllls are used which have arl expan6ion ratio of abollt 20. In the structllre paste accorc3ing to the irlventioll thec:e micropearls partially perfortn the function of the ~-lowillg ac~el~t ill the collventi(,)nal PVC plastisols.

These are ex~anded hc)llc~w polymef headq, in the surface of which inor~allic fillers are advanta~ec)uqly embedded. The diameter of such hc~llow microbeads is preferably in the range of 10 - ~0 ~m and their specific volume is about 0.15 g/cm~. Due to the polylller material of the microbead walls and the inorganic filler particles attached thereto, the hollow Illicrc~beads are practically a mixed or,cJanic-irlc)r~allic filler of very high specific vol~lme.
