Description

EXAMPLE 1

[0051] For producing a kit of semi-processed products, a process is carried out starting, for example, from 100 g of a reference white paint. There is provided a reference list of the components and the relative quantities thereof. The reference list comprises among the other components a quantity of titanium dioxide TiO.sub.2 and a quantity of fluid diluent, in this case water. The reference list obtained is as follows:

TABLE-US-00001 Water 25 g Filler 10 g TiO.sub.2 20 g Additives 4.5 g Thickening agents 0.5 g Binders 40 g

[0052] There is obtained from the reference list a main list by subtracting the listed quantity of titanium dioxide and a proportional quantity of water which is adapted to the optimum dispersion thereof. In this case, in order to optimally disperse 20 g of titanium dioxide, there is required 9 g of water. The main list, which is reproportioned with respect to 100 g of product, is as follows:

TABLE-US-00002 Water 23 g Filler 15.3 g Additives 5 g Thickening agents 0.7 g Binders 56 g

[0053] There is formulated with the main list a non-pigmented main semi-processed product which has components and relative proportional quantities which are equal to those listed in the main list, less the quantities of titanium dioxide and water which are eliminated from the reference list.

[0054] There is also formulated at least one pigmented subordinate semi-processed product which comprises titanium dioxide which is dispersed in water. The titanium dioxide does not necessarily have to be the same as the reference list but may be different. This pigmented subordinate semi-processed product has a white colour which is imparted by the titanium dioxide which in 100 g is present at 70% by weight and is dispersed in 30 g of water.

[0055] The combination of the two non-pigmented main and pigmented subordinate semi-processed products at sufficient proportions is capable of reproducing the reference white paint with the same quality.

EXAMPLE 2

[0056] A non-pigmented main semi-processed product which therefore does not contain titanium dioxide has been produced by mixing the following components:

[0058] A non-pigmented subordinate semi-processed product which is clear has been produced by mixing the following components:

TABLE-US-00005 Non-pigmented subordinate semi-processed product, clear Raw material Quantity in 1 kg Quantity in 100 cm.sup.3 DEMI WATER 199.8 31.071 PEG200 40 5.535 THYLOSE HX6000 2 0.207 BENTONE LT 2 0.180 BENTONE 27 2 0.173 DYNAWEED 200 12 1.867 OROTAN N4045 15 1.794 BARIUM SULPHATE 420 14.514 TEGO AIREX 902 4 0.622 POLICRIL 547 300 43.602 ACTICIDE MBS 1.8 0.272 ACTICIDE F 1.4 0.162 Total 1000.00 100.00

[0059] The commercial names of the above-indicated products are respective manufacturers.

[0060] There have further been provided two pigmented subordinate semi-processed products which are titanium slurry in which the titanium dioxide is concentrated to 70% by weight. One of the two titanium slurries contains titanium dioxide which has the commercial name Tioxide TR88 and which is produced by Huntsman. The other titanium slurry contains titanium dioxide which has the commercial name Ti-Pure R-942 and which is produced by DuPont.

[0061] Using the above semi-processed products, there have been produced various finished paints using the following colourants:

TABLE-US-00006 Colour Colourant Name Description index Red Chromaflo 807-0755 REE ES Organic Red PR 254 Blue Chromaflo 807-7055 EXE ES Blue PB 15:3 Yellow Chromaflo 807-1811 CNE Yellow Iron Oxide PY 42 Black Chromaflo 807-9957 BXE HS Lamp Black PBk 7

[0062] The gloss according to the norm UNI 9389 (ISO 2813-78) of the finished paints was measured using a glossmeter from Elcometer which is capable of measuring the gloss at angles of 20, 60 and 85. The results obtained are set out in the following table.

TABLE-US-00007 Main semi- processed product fill Clear Opaque Clear Opaque Gloss Gloss level TiO.sub.2 TiO.sub.2 filler filler Colourant 60 85 COLOUR (% v/v) (% v/v) (% v/v) (% v/v) (% v/v) (% v/v) (GU) (GU) WHITE 84 4 12 0 0 0 11 32 RED 84 4.6 9.3 1.2 0.7 0.2 11.5 33 BLUE 84 2 5.5 3 2.5 3 11 31 YELLOW 84 0 0 0 7.7 8.3 12.5 32.5 BLACK 84 0 0 7 4 5 9 32

[0063] The minimum differences encountered with respect to the gloss are practically indistinguishable with the naked eye.

[0064] Naturally, the principle of the invention remaining the same, the forms of embodiment and details of construction may be varied widely with respect to those described and illustrated, without thereby departing from the scope of the present invention.
