We claim:
1. A method for selecting coating formulations for a multi-layer coating for repair purposes, the multi-layer coating comprising a primer applied on a substrate, at least one base or top coat and, optionally, a clear coat, the method comprising the following steps:
providing one or more databases of colorimetric data relating to a set of formulations andor relating to constituents for a primer and base or top coat layers;
entering the calorimetric data of an object to be repaired into a computer having access to said database;
determining the formulation of the primer and of other layers of the multi-layer coating with the aid of the database, in such a way that the resulting colour of the multi-layer coating to be applied matches the colour of the object to be repaired using the lowest possible amount of coating material.
2. The method according to claim 1, wherein the formulation is determined by selecting from a given set of predetermined formulations.
3. The method according to claim 1, wherein the formulation is determined by calculating from a set of data of available constituents, e.g., K and S values.
4. The method according to claim 1, wherein a primer is selected or calculated which closely matches the colour of the object to be repaired.
5. The method according to claim 1, wherein the calorimetric data of the object to be repaired are measured from several, preferably three or more, angles and in that the database comprises data relating to the colorimetric data of the composition to be selected or determined at these angles.
6. The method according to claim 1, wherein a primer formulation admixed with top or base coat toners is selected or calculated.
7. The method according to claim 1, wherein the calorimetric data in the database comprises L*,a*,b* parameters according to the CIE Lab system.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A herbicidal composition comprising an active compound combination comprising (a) a substituted thien-3-yl-sulphonylaminocarbonyltriazolinone of formula
or salt thereof
and
(b) iodosulfuron-methyl-sodium
2. A method for controlling unwanted plants comprising allowing an effective amount of a composition according to claim 1 to act on the unwanted plants andor their habitat.
3. A composition according to claim 1 in which substituted thien-3-yl-sulphonylaminocarbonyltriazolinone is in the form of a sodium, potassium, magnesium, calcium, ammonium, C1-C4-alkylammonium, di-(C1-C4-alkyl)ammonium, tri-(C1-C4-alkyl)ammonium, tetra-(C1-C4-alkyl)ammonium, tri-(C1-C4-alkyl)sulphonium, C5 or C6-cycloalkylammonium, or di-(C1-C2-alkyl)benzyl ammonium salt.
4. A composition according to claim 1 in which substituted thien-3-yl-sulphonylaminocarbonyltriazolinone is in the form of a sodium salt.
5. A composition of claim 1, further comprising a safener (c).
6. A process for preparing a herbicidal composition comprising mixing a composition according to claim 1 with one or more surfactants andor extenders.
7. A method for selective, semi-selective andor nonselective control of monocotyledonous andor dicotyledonous plants comprising allowing an effective amount of a composition according to claim 1 to act on the monocotyledonous andor dicotyledonous plants andor their habitat.
8. A method of claim 7, wherein said plants are at least one selected from the group consisting of Chenopodium, Abutilon, Bromus, Veronica, Viola, Setaria, Avena, Alopecurus, Cyperus, Matricaria, Xanthium, Cassia, Ipomoea, Digitaria, Polygonum, Eriochloa, Gatium Eriochloa, and Lotium and said method is used to protect at least one crop selected from the group consisting of cotton, barley, potatoes, maize, oil seed, rape seed, rice, rye, soy beans, sunflower, wheat, sugarcane and sugar beet.
