SUBJECT
EXPERIMENTAL MONASTRAL BLUE G, BT-476-D iIN 0LE0RESIN0U3 INK
liftRODUCT TON:
Inkmakers are currently very interested in Cowles, dispersible blues vib-lch could replace flushed CPC blue, particularly in heatset publication
(process blue) ink. Flushed blue can be very costly on a moiiey/pound pigment basis ; Cowles dispersible products have obvious advantages in
money value, formulating flexibility and handling ease,
Monastral Blue G, BT-476-D :is a counterdfferlng for Clba-Cknigy 's "Irgalite"Blue LGLD, and is designed to replace - flushed CPC blue. .
This report covers initial publication heatsat.ink comparison of with'two commercially available green shade CPC blue flushes and Cowles dispersed LGLD. We also^iade three-roll mill comparisons of Lf-476-a with LGLD and Monastral Bme G, BT-4?3--D,
Wtuused serai-works BT-476-D,. submitted by Research and coded RW~73-eoW. '
CONCLuaTOHS:
> B'P-476-D, SW"73~G047.6 is .more Cowles -dispersible than, and superior ttnctorlally to, Clba-Gelgy's IGLD. When printed over
diary!id's yellow, BT-476-D is superior tinctorialj.y to LGLD and the two commercial flushed blues tested.
BfP-476-D is an excellent replacement for BT-473-D In three-roll 5:.i 11 - applications.

Coxvles Performance
/
At equal millbase pigmentation, BT-476-D develops leas heat than, , and has texture equal to, LGLD, When BT-476-D loading is increased 10$,
its heat development is equal to LGLD, and texture remains the same, BT-476-D texture improves at even higher millbase loadings.'
Versus LGLD, BT-4-76-D in mas stone is generally dark, intense and transparent, and in tint green, slightly less intense and equal to 2,5$ weak in strength.
Process Printing
We made equal pigment Tandercook proof press prints of BT~476~D,
LGLD, and the two flushed blues over diarylide yello^'to simulate process
printing,
.;
Versus LGLD, the green produced by BT-476-D is dark and blue,
indicating pigment could be removed from the
ink.
i'
Versus Chemetron's Flushed Phthalo Blue GS, PS-1116, the green
from BT-476-D is light, yellow and intense; carbon black could be added
to the BT-476-D ink.
The green produced by Hilton-Davis * Peacoline Blue 5-66-K-319 is dark and much less intense than the BT-476-D green; this is probably due to the competitive's redder shade.
> Versus Flushed Blue
iiiiii-r-Tniirn-pi n-lTir-----"-iti
------ -------^
BT-476-D has superior money value versus the two flushes at their list price,.
Versus Chemetron'o FS-III6, BT^76~D in masstone is dark, intense and very slightly opaque, and in tint slightly red, very slightly less
in tense and 3.2.5$ strong.
Against Hllton-Davis* 5-66-H-319* BT-476-D in macstone is dark, intense and slightly opaque, and in tint very slightly green and 10$ weak. We beleive this competitive may contain red shade (alpha) blue, which would explain its shade and strength.
Three-Roll Mill
Texture and texture development of BT-476-D are about equal to BT--473-D and slightly inferior to LGLD.
Versus EP-473-D, BT-476-D in masstone is very slightly red, very slightly dark and bronzy, end in tint very slightly red,, slightly less intense and 2.5$ strong.
Bf-476-B is very close to LGLD in color and strength.

DISCUSSION;
*
*
We will continue work to develop optimum grind conditions for
BT-476-D and will make adjusted prints of BT-476--D versus LGLD and
flushed colors.
.
*'
We will hold this work request open to test plant BT-476-D when available,
